Working days = all days between start and end, minus Saturdays and Sundays
The calculator steps through the period day by day and counts every day that isn’t a Saturday or Sunday. National public holidays are not automatically subtracted, since these differ by country and year.
計算例
Monday 20 July through Friday 24 July 2026
→ 5 working days.
よくある間違い
- Forgetting that national public holidays are not subtracted, even when they fall on a weekday.
Limitations
- Public holidays are not accounted for; subtract them yourself if relevant.
活用シーン
- Planning a delivery time or project deadline in working days.
