[ date->day ]

Method

[Date->Day] is an accessor for getting or setting the day of month field for a date object. [Date->Day] is a synonym for [Date->DayOfMonth]

Getting uses no parameters and returns the day of month as an integer.

Setting requires an integer parameter, and supports the =, += and -= operators. Setting modifies the date object in-place, but does not return a value.

  • Syntax
Date Object->day
Date Object->day=Integer
Date Object->day+=Integer
Date Object->day-=Integer
Examples

To get or set the day of month field of a date object:

Use the [Date->Day] method. The following example uses a single date object, then gets the day of month and returns its value.

Next we set the day of month field to a new value using the = operator, then set it again by adding 1 to the day of month using the += operator, and set it once more by subtracting 1 from the day of month using the -= operator. We return the result for each set operation.

Code

local('d') = date('2011-02-21')
#d->day + '<br>'
#d->day=5
#d + '<br>'
#d->day+=1
#d + '<br>'
#d->day-=1
#d

Result
