What's the difference between "inclusive" and "exclusive" when counting the two dates?
"Exclusive" counts only the number of days between the two dates (like counting nights between two dates). "Inclusive" adds one day to include the start date itself in the count — useful, for example, when calculating "number of vacation days" that start and end on specific dates and you want the start day included.
How are business days calculated?
Excluding Friday and Saturday (the official weekend in Saudi Arabia), without excluding other official holidays and occasions (like the two Eids and National Day) since these change yearly and require an updated official calendar.
What if I enter the end date before the start date by mistake?
The calculator automatically swaps the two dates to calculate the correct difference, and notifies you of this within the result — no need to worry about input order.
Why does "approximate years" differ from "years, months, and days" in the result?
The exact difference (year/month/day) respects actual month and year lengths (28-31 days, leap year or not). "Approximate years," on the other hand, is a simplified division of total days by the average year length (365.25 days) — useful for quick comparison only.
Can this be used to calculate days remaining until a future occasion?
Yes, enter today's date as the start and the occasion's date as the end (or vice versa) and you'll get the exact count in all units.
