Ext.date is a singleton class that encapsulates a series of date manipulation functions, extending the functionality of JavaScript date, with some common features listed below.

Ext.Date.add (date, interval, value) increases or decreases the time for date, which does not change the value of the original Date object, but instead returns a new Date object.

Ext.Date.between (date, start, end) determines whether the date is between start and end.

Ext.Date.clearTime (date, clone) sets the time of date to 00 hours, 00 minutes, 00 seconds, 000 milliseconds.

Ext.Date.clone (date) clones a copy of the date.

Ext.Date.format (date, format) formats the date and returns the formatted string.

Ext.Date.getDayOfYear (date) Gets the date that is the day ordinal of the year.

Ext.Date.getDaysInMonth (date) Gets the date that is the day ordinal of the month.

Ext.Date.getFirstDateOfMonth (date) Gets the first day of the month in which the date is.

Ext.Date.getFirstDayOfMonth (date) Gets the week of the first day of the month in which the date is.

Ext.Date.getLastDateOfMonth (date) Gets the last day of the month in which date is located.

Ext.Date.getLastDayOfMonth (date) Gets the week of the last day of the month in which the date is.

Ext.Date.getWeekOfYear (date) Gets the number of weeks in the year in which the date is.

Ext.Date.isLeapYear (date) the year in which the date is in leap years.

Ext.Date.now () returns the number of milliseconds for the current time to January 1, 1970. There are already date.now () implementations of the same functionality in Chrome, IE9, and Ie10.

Ext.Date.parse (input, format, strict) creates a date based on the input string, and Date.parse () has a similar function.
