Am trying to get all the events in my calendar and i come up with the below code. But the problem is am getting only one event from the calender.(i.e, event which is nearby). can someone please help me where am going wrong and suggest me a way. Thanks in advance.
var cal = CalendarApp.getAllOwnedCalendars();
Logger.log("Length is :" +cal.length);
for(var i=0; i<cal.length;i++)
{
var cid = cal[i].getEvents(now, later) ;
Logger.log(cid[i].getTitle());
}
You can't get all the events if you don't know the end date. There is no way to determine the end date. You can retrieve all the events for today:
// Determines how many events are happening today.
var today = new Date();
var events = CalendarApp.getDefaultCalendar().getEventsForDay(today);
Logger.log('Number of events: ' + events.length);
for(var i=0; i<cal.length;i++) {
var eventTitle = events[i].getTitle();
Logger.log('eventTitle: ' + eventTitle);
}
You could set an end date that was many years into the past I suppose.
var now = new Date();
var later = new Date(2010, 0, 1);
Sets the later date to Jan. 1st, 2010
I have pasted the code below. To explain what the code is intended to do is block out a conference room so that it can not be reserved for use, it is a small "huddle room" that will be blocked out and only available to reserve a week in advance.
Anyway here is the problem I am encountering with the code below. If I run the code starting from Jan 1. The code will run and then part way through March stops creating events, if this happens exactly at the beginning of a month it wouldn't be an issue as I could either start easily from that point again, or assume the month is spelled wrong. But it creates reservations though march 18th. Also when I restarted this and set it to create blocked reservations starting at the beginning of April it got though December 8th.
My first guess is that I need to deal with reformatting the code to handle months without 31 days, but I assumed that those none existent days would just throw an error and the lop would continue, and it did get through February which is a short month.
Just thinking maybe someone who has more experience with Google Scripting may have an idea or see a flaw in something I am doing. Thanks for any help
function blockReservations(){
var roomcalendar = CalendarApp.getCalendarById('company.com_12458546525839392d898932#resource.calendar.google.com');
//for(var z=2014;z<=2020;z++){
//var year = z;
var year = '2014'; //This Line May be used in place of the above for loop to specify a specific year
for(var x=4;x<=12;x++)
{
if(x==1) var month = 'January';
else if(x==2) var month = 'February';
else if(x==3) var month = 'March';
else if(x==4) var month = 'April';
else if(x==5) var month = 'May';

else if(x==7) var month = 'July';

else month = 'null';
//var month = 'July'; //This Line May be used in place of the above for loop to specify a specific year
for(var y=1;y<=31;y++)
{
var date = y;
var startDateString = month + ' ' + date + ', ' + year +' 00:00:00';
var endDateString = month + ' ' + date + ', ' + year +' 24:00:00';
var event = roomcalendar.createEvent('Time Blocked', new Date(startDateString), new Date(endDateString));
}
}
// }
}
You don't mention any error messages, but I would expect that you're receiving a notification email reporting that the script was killed for running too long. Creating events in a loop can take lots of processing time.
I propose a different approach. Instead of creating daily events to reserve the room, why not create a recurring all-day event, starting a number of days in the future. Then each day, this reservation can be updated (by a timed trigger function) to revise the recurrence rule to start one day later.
/**
* Create or update a block reservation for a conference room,
* starting 'blockFrom' days from today.
*/
function updateBlockReservation() {
// Get Calendar
var calName = 'Huddle Room';
var cal = CalendarApp.getCalendarsByName(calName)[0];
var title = 'Reserved'; // Reserved events will have this title
var blockFrom = 7; // Days from now until room is blocked
var today = new Date(); // Today's date, ...
today.setHours(0,0,0,0); // at midnight.
var startDate // Daily block reservation starts here
= new Date(today.getTime() + (blockFrom * 24 * 60 * 60 * 1000));
var endTime = new Date(startDate.getTime() + (24 * 60 * 60 * 1000) - 1);
var recurrence = CalendarApp.newRecurrence().addDailyRule();
// Look for existing block reservation
var series = cal.getEvents(startDate, endTime, {search:title});
if (series.length == 0) {
// No block reservation found - create one.
var reserved = cal.createAllDayEventSeries(title, startDate, recurrence);
}
else {
// Block reservation exists - update the recurrence to start later.
reserved = series[0].getEventSeries();
reserved.setRecurrence(recurrence, startDate);
}
debugger; // Pause if running in debugger
}
I want to use the calendar timezone to set the time zone of a date object. I'm looking for the proper technique. We have several bases around the nation, and each has their own calendar for journal and daily activities. We have multiple scripts that post to the calendars. I want to use the timezone of the calendar to set the date Object timezone, because the users travel around to different bases, and their computers might not be set to the correct time zone. We want to avoid incorrect time settings.
Should the script's timeZone be set to UTC?
This is where I'm currently at:
function submitUiTest(e) {
var app = UiApp.getActiveApplication();
var cal = CalendarApp.getCalendarById('calendarId');
var timeZone = cal.getTimeZone();
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheet = ss.getSheetByName('Sheet1');
var startTime = e.parameter.startDate
startTime.setHours(e.parameter.startHour, e.parameter.startMin, 0)
startTime = formatTime(startTime, timeZone);
Logger.log(startTime)
var endTime = e.parameter.endDate
endTime.setHours(e.parameter.endHour, e.parameter.endMin, 0);
endTime = formatTime(endTime, timeZone);
Logger.log(endTime)
cal.createEvent('TimeZone Test', new Date(startTime), new Date(endTime));
ss.appendRow([startTime, endTime]);
return app;
}
function formatTime(time, timeZone){
return Utilities.formatDate(time, (timeZone-time.getTimezoneOffset()), 'M/d/yyyy HH:mm');
}
Edit:
Currently there are 3 calendars, they are not user calendars, just each a separate calendar created for individual Air Stations. The air stations are each in separate time zone's. As crew members work at these stations they post daily activities to the calendars, and there are also several Ui scripts we have that post to the same calendars ex. a flight log. When an entry to a calendar is posted to any calendar, the time relates only to the timezone set on the script, not the timezone on the calendar. When the date or timestamp object is created, how can I use the timeZone that the calendar itself is set to.
What is best practice for scripts that record dates for different time zones?
Set the script timezone to UTC and do the conversion?
What do you use to get the user's timezone or in this case, I don't care what the user's timezone is set too, I need to use the timezone of the calendar.
Here is a modified version of the answer, without the UI stuff:
function gasTimezoneOffset(date, hour){
var cal,calTimeZone,calTz,date,dateString,scriptTimeZone,sessionTz;
var testMonth = "March",
testDayOfMnth = "26",
testYr = "2016",
hour = "10:00",
timeZoneDiff = 0;
Logger.log("Script Time Zone: " + Session.getScriptTimeZone());
dateString = testMonth + " " + testDayOfMnth + ", " + testYr;
Logger.log("dateString: " + dateString);
date = new Date(dateString);
cal = CalendarApp.getDefaultCalendar();
calTimeZone = cal.getTimeZone();
calTimeZone = Utilities.formatDate(date, calTimeZone, 'Z');
scriptTimeZone = Utilities.formatDate(date, Session.getTimeZone(), 'Z');
calTz = Number(calTimeZone.slice(0,3));
sessionTz = Number(scriptTimeZone.slice(0,3));
//If both time zones are the same sign, get the difference between the
//two. E.g. -4 and -2. Difference is 2
//if each time zone is a different sign, add the absolute values together.
//-4 and +1 should be 5
if (calTz < 0 && sessionTz > 0 || calTz > 0 && sessionTz < 0){
timeZoneDiff = Math.abs(Math.abs(calTz) + Math.abs(sessionTz));
} else {
timeZoneDiff = Math.abs(Math.abs(calTz) - Math.abs(sessionTz));
};
hour = Number(hour.slice(0,2));
return hour + timeZoneDiff;
};
EDIT : I wrote a small test UI and ran it with 2 calendars in 2 different timezones.
Calendar events are created in the Calendar timezone and the user interface shows user values. Google takes care of timezone settings in both calendars and I didn't notice any anomalies : events where created as I wanted to, ie at the time shown in the UI in the calendar Timezone.

Logger.log(sessionTz)
Logger.log(timeZone)

first comment :
I began to write a comment to ask you some questions but it was getting too long... so please consider this as a comment, not an answer ;-).
I'm not sure I understand what you say about 'their computer not being set to the right timezone' the timezone of their computer is not relevant if they use Google Calendar, it is only a matter of parameter in Google Cal. If I understood your goal is that if the script sets an appointment at 8:00 AM they will see it shown at 8:00 AM in their Calendar wherever they are (8:00 AM in their 'local' timezone), right ?
So to summarize, you are running this script from one place and creating events for people in other timezones in their own calendars ? And are the users moving across different timezones ? These are 2 separate questions and it doesn't have one single solution.
If a single user is moving across timezones all the events will be shifted unless he doesn't change his GCal parameters. But if he does so he won't be notified at the right time and the Calendar interface will be out of time... so that's not a reasonable solution.
My last question : when you create an event in another calendar (in another tz) can it be an appointment between you and this person ? in other words is the absolute time of any importance for you use case ?
Ok here is a solution to the problem. I've probably went way out of my way or missed something simple but this finally works like I was hoping. Feel free to critique. I set the webapp timezone to GMT-0000 just for simplicity.

Could try deploying a separate web app for each time zone. Set the time zone of each app to match that of the unique calendar they are linked to. Since you only have 3 calendars in different time zones, seems like it would work for your case.
Google scripts doc states CalendarEventSeries should have at least two methods setRecurrence(). When I'm trying to use it:
setRecurrence(new Date(), CalendarApp.newRecurrence().addYearlyRule().interval(1));
I'm getting this error:
Cannot find method (class)setRecurrence(object,$Proxy754). (line 60,
file "Sync").
The method is invoked on CalendarEventSeries for sure. How to resolve that error?
The example you show applies to all day Events (specifying only one date for the first occurrence), are you applying to such an event or to a 'normal' event ?
In this last case you should provide 2 dates (start and end) for the first occurrence.
The link above shows the documentation that is pretty clear about it...
Here is an "end-to-end" example that shows how it works, the first function creates an event with a yearly recurrence starting today, the second one changes this recurrence to be daily, starting today...
It uses your default calendar
function createTestSerie(){
var cal = CalendarApp.getDefaultCalendar()
if (cal) {
var title = 'Test Event';
var desc = 'Created using Google Apps Script';
var loc = 'Here, there and everywhere...';
var recur = CalendarApp.newRecurrence().addYearlyRule().interval(1)
var start = new Date();
var end = new Date(start.valueOf()+3600*1000);
var event = cal.createEventSeries(title, start, end,recur,{description:desc,location:loc});// event will be every year and last 1 hour
}
}
function modifyRecurrence(){
var cal = CalendarApp.getDefaultCalendar()
if (cal) {
var start = new Date();
var end = new Date(start.getTime()+3600*1000*2);
var events = cal.getEvents(new Date("February 16, 2013 08:00:00 PDT"), new Date("February 19, 2013 08:00:00 PDT"))
for(i in events){
if(events[i].getTitle()=='Test Event'){
var recur = CalendarApp.newRecurrence().addDailyRule().interval(1)
var eventId = events[i].getId()
cal.getEventSeriesById(eventId).setRecurrence(recur, start, end);// now events will be lasting 2 hours evey day starting today
}
}
}
}
EDIT following your comment : It works exactly the same for allDayEvents, here is a modified example code :
function createAllDaySerie(){
var cal = CalendarApp.getDefaultCalendar()
if (cal) {
var title = 'All Day Test Event';
var start = new Date();
var desc = 'Created using Google Apps Script';
var loc = 'home';
var recur = CalendarApp.newRecurrence().addYearlyRule().interval(4)
var start = new Date();
var event = cal.createAllDayEventSeries(title, start,recur,{description:desc,location:loc});// event will be every 4 years starting today
}
}
function modifyAllDayRecurrence(){
var cal = CalendarApp.getDefaultCalendar()
if (cal) {
var start = new Date("February 19, 2010 08:00:00 PDT");// here you can choose any date you like that will be the new start date.
var events = cal.getEvents(new Date("February 16, 2013 08:00:00 PDT"), new Date("February 22, 2013 08:00:00 PDT"))
for(i in events){
if(events[i].getTitle()=='All Day Test Event'){
var recur = CalendarApp.newRecurrence().addYearlyRule().interval(1)
var eventId = events[i].getId()
cal.getEventSeriesById(eventId).setRecurrence(recur, start);// now events will occur once a year starting on february 19, 2010 (see screen capture below)
}
}
}
}
And we have the solution for my problem. There is a bug in API documentation. It is written there:
method setRecurrence(startDate, recurrence)
Changes the recurrence rules of this series to a new rule, and to an all day event.
But in fact method setRecurrence() takes those arguments in upside down order:
method setRecurrence(recurrence, startDate)
Many thanks to Serge for help, it was crutial! Unfortunately without reputation 15 I'm not able to give you any points :(
I have created a Ui on a Google Sites page with a date field (date picker). Is there a way to pre-populate it with the current date? Secondly, is there a way of isolating the year from the date picked? Here is the code I have so far:
//Create elements for vPanel_01
var labelDate = app.createLabel("Date of event:");
var textBoxDate = app.createDateBox().setName("date").setStyleAttribute("color", "#a7a7a7");
I'd like to isolate the year from the input so that I can use for comparisons in the script.
Is there a way to pre-populate it with the current date?
The following code does the required.
var now = new Date();
var labelDate = app.createLabel("Date of event:");
var textBoxDate = app.createDateBox().setName("date").setStyleAttribute("color", "#a7a7a7").setValue(now);
is there a way of isolating the year from the date picked?
Please explain what do you expect to have by writing isolating the year from the date picked? Do you need to extract a year of a date? If yes, the the following does it.
function doGet(e) {
var app = UiApp.createApplication();
var now = new Date();
app.add(app.createLabel('Current Year: ' + now.getFullYear()));
return app;
}
The code which extracts year from a date box.
function doGet(e) {
var app = UiApp.createApplication();
var now = new Date();
var dateBox = app.createDateBox().setName('datebox').setValue(now);
var label = app.createLabel(now).setId('label');
var handler = app.createServerHandler('onBtnClick');
handler.addCallbackElement(dateBox);
var btn = app.createButton('Click Me').addClickHandler(handler);
app.add(dateBox);
app.add(label);
app.add(btn);
return app;
}
function onBtnClick(e) {
var selectedDate = new Date(e.parameter.datebox);
var year = selectedDate.getFullYear();
var app = UiApp.getActiveApplication();
var label = app.getElementById('label');
label.setText('Selected Date: ' + selectedDate + ', Year: ' + year);
return app;
}
Following your comment : if I keep megabytes1024's example you should add an handler to the textBox (or to a button hat validates the input) and a callBackElement to this handler and then, in the handler function you can use something like this :
var dateObject = new Date(e.parameter.date); // 'date' is the name of the datepicker
When you have this date object you can get whatever you want from it, for example :
var fullyear = dateObject.getFullYear(); // will return full year in 4 digits
see doc on date object
You could be interested in this example as well.
