Practical guidance

How to count business days between two dates

Use this weekday calculator to plan simple deadlines. It counts Monday through Friday and separately reports calendar days and weekends.

  1. Select the start and end dates, then choose whether to include both endpoints. The checkbox is on by default.
  2. For example, Thursday 1 October to Monday 5 October 2026 has 5 calendar days: 3 business days and 2 weekend days when both endpoints are included.
  3. If you untick Include both end dates, the starting Thursday is excluded, leaving 2 business days in that example.

Public holidays, country-specific workweeks and business closures are not considered; adjust results manually if deadlines depend on them.
