Examples

Anchor
function_mc_date function_mc_date

MC Function: Date  

Format

Date( object,  format )

Arguments Types

Return Type

Returns Value

• Makes an attempt to convert the string that is contained in object using the format, to type Date.

• The format string can contain the following special symbols:

  • object – String

  • format – String

  • y – For year representation.

  • m – For month representation.

  • d – For day in the month representation.

• The number of consecutive special letters indicates the maximum number of digits in the corresponding area.
  For example, mm indicates that the number of the month contains at a maximum, two digits, but it can contain less too. All of this is done to enable the leading zeroes to be omitted. If any of these fields are omitted, the default values of the current date are taken. Other symbols in the format string are not taken into consideration, but the corresponding symbol must be present in the date string too. Otherwise, the date is considered to be in the incorrect format.
  For example, date('14.05.1973', 'dd/mm/yyyy') causes an error because the delimiter in the format does not match the actual one in the date ('.' instead of '/'). If the given data is an incorrect date, the object is marked as containing an invalid date.
