తరచుగా అడిగే ప్రశ్నలు
Does the calculation include both start and end dates?
Usually not. The result is the number of complete days between. For example, Mon–Tue = 1 day.
How do leap years affect the count?
Leap years (divisible by 4, except centuries not divisible by 400) add February 29. The calculator handles this automatically.
What about time zones?
Days are calendar days regardless of time zone. Time differences affect hours/minutes; date calculations count calendar days.
