Comprehensive Calculator Guide
This calculator counts the working days between two dates after taking out the weekend, using the Friday–Saturday weekend of Saudi Arabia by default. October 2026 has 31 days, of which 21 are working days. Use it for processing deadlines, delivery times and project plans.
Weekends and public holidays
Both the start and end dates are included. October 2026 starts on a Thursday and has five Fridays and five Saturdays, so 31 − 10 = 21 working days; with a Saturday–Sunday weekend it would be 22.
Public holidays such as Founding Day (22 February), National Day (23 September) and the two Eids are not removed, since their length varies by sector and the Eids follow the Hijri calendar. Subtract any that fall in your period.
