How working days are counted

Working days = Calendar days − Weekly off days − Holidays on working days

Choose the weekly-off pattern that matches your organisation:

  • Saturday & Sunday: most offices and IT companies.
  • Sunday only: many shops, factories and six-day workplaces.
  • Sunday + 2nd & 4th Saturday: Indian banks, as mandated by RBI and IBA. The 1st, 3rd and 5th Saturdays are working days.
  • Friday & Saturday: the weekend in some Gulf countries.

Example

October 2026 has 31 days. With Saturday–Sunday weekends there are 22 weekdays. Excluding Gandhi Jayanti (2 October) and a festival holiday on 20 October leaves 20 working days.

Adding holidays

Paste your company or state holiday list, one date per line in YYYY-MM-DD format. National holidays (26 January, 15 August, 2 October) are the same everywhere, but festival and state holidays vary, so use your own organisation's calendar.
