[Date->DayOfWeek] is an accessor for getting or setting the day of week field for a date object.
Getting uses no parameters and returns the day of week as an integer (1=Sunday, 7=Saturday).
Setting requires an integer parameter, and supports the =, += and -= operators. Setting modifies the date object in-place, but does not return a value.
Date Object->dayofweek Date Object->dayofweek=Integer Date Object->dayofweek+=Integer Date Object->dayofweek-=Integer
Use the [Date->DayOfWeek] method. The following example uses a single date object, then gets the day of week and returns its value.
Next we set the day of week field to a new value using the = operator, then set it again by adding 1 to the day of week using the += operator, and set it once more by subtracting 1 from the day of week using the -= operator. We return the result for each set operation.
local('d') = date('2011-02-21') #d->dayofweek + '<br>' #d->dayofweek=5 #d + '<br>' #d->dayofweek+=1 #d + '<br>' #d->dayofweek-=1 #d
