Business days calculator

Count working days between two dates, skipping weekends and holidays you list yourself.

Dates stay in this browser. Saturdays and Sundays are treated as weekend days; holidays come only from the list you enter.

One date per line, or separated by commas — YYYY-MM-DD. Up to 5,000 dates.

Choose a start and end date.

How to use

  1. Enter the start and end dates.
  2. Add any holidays as YYYY-MM-DD lines.
  3. Calculate and read the breakdown.

What it supports
