Date Formatting Methods

Formatting and Parsing

There are several predefined methods for date formatting that can be used to convert dates to strings and strings to dates

Convert dates to strings

var str1 = webix.i18n.dateFormatStr(date_obj);  //date
var str2 = webix.i18n.longDateFormatStr(date_obj);//long date representation
var str3 = webix.i18n.timeFormatStr(date_obj);  //time
var str4 = webix.i18n.fullDateFormatStr(date_obj);//date + time
var str5 = webix.i18n.parseFormatStr(date_obj);  //used for date serialization

Convert strings to dates

var date1 = webix.i18n.dateFormatDate(string);  //date
var date2 = webix.i18n.longDateFormatDate(string);//long date representation
var date3 = webix.i18n.timeFormatDate(string);  //time
var date4 = webix.i18n.fullDateFormatDate(string);//date + time
var date5 = webix.i18n.parseFormatDate(string);  //used for date parsing

Formats can be defined by locales to adapt numbers and dates to the target location.

If necessary, you can create your own conversion methods:

Custom date convert

var format = webix.Date.dateToStr("%Y.%m");
var string = format(new Date()); //2012.05

var parser = webix.Date.strToDate("%Y.%m");
var date = parser("2012.05");

Supported Format Options

%d - the day as a number with a leading zero (01 to 31)
%j - the day as a number without a leading zero (1 to 31)
%D - the day as an abbreviation (Sun to Sat)
%l - the day as a full name (Sunday to Saturday)
%m - the month as a number with a leading zero (01 to 12)
%n - the month as a number without a leading zero (1 to 12)
%M - the month as an abbreviation (Jan to Dec)
%F - the month as a full name (January to December)
%y - the year as a two-digit number (00 to 99)
%Y - the year as a four-digit number (1900�9999)
%h - the hour based on the 12-hour clock with a leading zero (00 to 11)
%g - the hour based on the 12-hour clock (0 to 11)
%H - the hour based on the 24-hour clock with a leading zero (00 to 23)
%G - the hour based on the 24-hour clock (0 to 23)
%i - the minute as a number with a leading zero (00 to 59)
%s - the second as a number with a leading zero (00 to 59)
%S - the milliseconds as a number with a leading zero (000 to 999)
%a - displays am (for times from midnight until noon) and pm (for times from noon until midnight)
%A - displays AM (for times from midnight until noon) and PM (for times from noon until midnight)
%c - displays date and time in the ISO 8601 date format (e.g. 2015-10-04T05:04:09)

For instance, “%d-%F-%Y,%D” will display the date as 11-September-2012, Tue.

strings like 20120502, where there are no separators between numbers, can't be parsed as dates.
