[ date->dayOfYear ]

Method

[Date->DayOfYear] is an accessor for getting or setting the day of year field for a date object.

Getting uses no parameters and returns the day of year 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->dayofyear
Date Object->dayofyear=Integer
Date Object->dayofyear+=Integer
Date Object->dayofyear-=Integer
Examples
  • Beginner

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

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

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

Code

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

Result
