    • date - (Date) the date object that you need to add a time to/subtract a time from
    • number - (number) the number of units to add. If this number is positive - the time will be added to the date, if negative - the time will be subtracted
    • unit - ('minute', 'hour', 'day', 'week', 'month', 'year') the time unit
//adds 1 year to the specified date: 29 June, 2019 -> 29 June, 2014
var newDate = scheduler.date.add(new Date(2019, 05, 29), 1, 'year');
  • convert_to_utc(date) - converts local time to UTC
    • date - (Date) the date object to convert
//29 June, 2019 14:00 (local time) -> 29 June, 2019 12:00 (utc)
var time = scheduler.date.convert_to_utc(new Date(2019, 05, 29, 14, 00));
  • copy(date)- makes a copy of a Date object
    • date - (Date) the date object to copy
var copy = scheduler.date.copy(new Date(2019, 05, 29));// -> 29 June, 2019
  • date_part(date) - resets the time part of the provided date to 00:00:00
    • date - (Date) the date object to format
//29 June, 2019 14:30:10 -> 29 June, 2019 00:00:00
var date = scheduler.date.date_part(new Date(2019, 05, 29, 14, 30, 10));
  • date_to_str(format, utc) - returns a function that converts a Date object to a string of the specified format

    • utc - (boolean) specifies whether local time should be converted to UTC
var formatFunc = scheduler.date.date_to_str("%d/%m/%Y");
var date = formatFunc(new Date(2019, 05, 29)); // -> "29/06/2019"
  • day_start(date) - resets the time part of the provided date to 00:00:00. Alias of the date_part method. Used by the Day view to set the display date and can be redefined to provide the default behaviour

var date = scheduler.date.day_start(new Date(2019, 05, 29, 14, 30, 10));
  • getISOWeek(date)- returns the week number of the date
    • date - (Date) the date object to format
var week = scheduler.date.getISOWeek(new Date(2019, 05, 29)); // ->26
  • getUTCISOWeek(date) - returns the week number of the date, but previously converts local time to UTC

    • date - (Date) the date object to format
//29 June, 2019 14:30 -> 01 June, 2019 00:00
var firstDay = scheduler.date.month_start(new Date(2019, 05, 29, 14, 30));
  • str_to_date(format,utc,parseExact) - returns a function that converts a string of the specified format to a Date object

    • utc - (boolean) specifies whether local time should be converted to UTC
    • parseExact - (boolean) defines whether Scheduler identifies the format of a date automatically (false, default) or uses the format passed a user (true)
var formatFunc = scheduler.date.str_to_date("%d/%m/%Y");
var date = formatFunc("29/06/2019"); // -> 29 June, 2019 00:00:00
  • time_part(date) - returns the time of a Date object as a number of seconds counted from the midnight (00:00:00)
    • date - (Date) the date object to format
var time = scheduler.date.time_part(new Date(2019, 05, 29, 14, 30, 10));
//time -> 52210

    • num - (number) the number to format
var num1 = scheduler.date.to_fixed(2);// ->"02"
var num2 = scheduler.date.to_fixed(10);// ->10
