Nesne yönelimli kullanım

public IntlCalendar::add(int $field, int $amount): bool

Yordamsal kullanım

intlcal_add(IntlCalendar $cal, int $field, int $amount): bool

Add a signed amount to a field. Adding a positive amount allows advances in time, even if the numeric value of the field decreases (e.g. when working with years in BC dates).

Other fields may need to adjusted – for instance, adding a month to the 31st of January will result in the 28th (or 29th) of February. Contrary to IntlCalendar::roll(), when a value wraps around, more significant fields may change. For instance, adding a day to the 31st of January will result in the 1st of February, not the 1st of January.

The signed amount to add to the current field. If the amount is positive, the instant will be moved forward; if it is negative, the instant will be moved into the past. The unit is implicit to the field type. For instance, hours for IntlCalendar::FIELD_HOUR_OF_DAY.
