İki tarih arasındaki gün, hafta, ay veya yıl sayısını hesaplayın.
The simplest way to find days between dates is to convert both dates to a day count from a fixed reference point, then subtract. Our calculator does this automatically for any pair of dates.
Common uses for date calculations: counting days until a deadline or event, calculating someone's age in days, determining contract durations, figuring out when a payment is due, and calculating how many shopping days until a holiday.
Adding months is trickier than adding days because months have different lengths. Adding 1 month to January 31 is ambiguous — some systems use February 28, others use the last day of the target month. Our calculator uses the standard approach of adjusting to the last valid day of the month.
