       date, is a three-integer array, day, month, and year, in the format of perl localtime (
       see "localtime" in perlfunc ) - day can be in range from 1 to 31,month from 0 to 11, year
       from 0 to 199.

API

   Events
       Change
           Called when the date property is changed.

   Properties
       date DAY, MONTH, YEAR
           Accepts three integers in format of "localtime".  DAY can be from 1 to 31, MONTH from
           0 to 11, YEAR from 0 to 199.

           Default value: today's date.

       day INTEGER
           Selects the day in month.

       firstDayOfWeek INTEGER
           Selects the first day of week, an integer between 0 and 6, where 0 is Sunday is the
           first day, 1 is Monday etc.

           Default value: 0

       month
           Selects the month.

       useLocale BOOLEAN
           If 1, the locale-specific names of months and days of week are used.  These are read
           by calling "POSIX::strftime". If invocation of POSIX module fails, the property is
           automatically assigned to 0.

           If 0, the English names of months and days of week are used.

           Default value: 1

           See also: date_as_string

       year
           Selects the year.

   Methods
       can_use_locale
           Returns boolean value, whether the locale information can be retrieved by calling
           "strftime".

       month2str MONTH
           Returns MONTH name according to useLocale value.

       make_months
           Returns array of 12 month names according to useLocale value.

       day_of_week DAY, MONTH, YEAR, [ USE_FIRST_DAY_OF_WEEK = 1 ]
           Returns integer value, from 0 to 6, of the day of week on DAY, MONTH, YEAR date. If
           boolean USE_FIRST_DAY_OF_WEEK is set, the value of "firstDayOfWeek" property is taken
           into the account, so 0 is a Sunday shifted forward by "firstDayOfWeek" days.

           The switch from Julian to Gregorian calendar is ignored.

       date_as_string [ DAY, MONTH, YEAR ]
           Returns string representation of date on DAY, MONTH, YEAR according to useLocale
           property value.

       date_from_time SEC, MIN, HOUR, M_DAY, MONTH, YEAR, ...
           Copies date from "localtime" or "gmtime" result. This helper method allows the
           following syntax:

                   $calendar-> date_from_time( localtime( time));
