$day

Usage: $day(date[,date_order])

Category: information

Implemented: Picard 2.7

Description:

Returns the “day” portion of the input date.

The “year”, “month” and “day” portions of the date must be entered as numbers, and can be separated by any non-numeric characters. The default order for the input date is “ymd”. This can be changed by specifying a date_order of either “dmy” or “mdy”. If anything other than “ymd”, “dmy” or “mdy” is specified, the default order “ymd” will be used.

Example:

The following statements will return the values indicated:

$set(foo,07.21.2020)
$set(bar,mdy)
$day(%foo%,%bar%)           ==>  "21"

$day(2020 07 21)            ==>  "21"
$day(2020.07.21)            ==>  "21"
$day(2020-07-21)            ==>  "21"
$day(2020-07-2)             ==>  "2"

$noop( Invalid date order)
$day(2020-07-21,dym)        ==>  "21"

$day(,)                     ==>  ""
$day(-07-2020,dmy)          ==>  ""
