Tanzania Working Days Calculator

Count working days between two dates in Tanzania, excluding weekends and 2026 public holidays.

Working days in Tanzania — what counts

"Working days" in Tanzania normally excludes Sundays and 14 public holidays. Saturdays are a half-day or full work day depending on the sector — banking and government close at 12:30; retail and most private firms run a full Saturday. This calculator lets you toggle Saturday inclusion to match your sector.

Common use cases

  • Project planning — number of working days between contract start and delivery.
  • HR — leave, notice periods, probation periods (typically 6 months working).
  • Court & legal — most Tanzanian statutes count working days, not calendar.
  • Tax filings — return-due windows. Pair with the Tax Calendar 2026.

2026 long weekends to plan around

  • April 3–6 — Good Friday + Easter Monday (4-day weekend).
  • April 26 (Sunday) → 27 (observed Mon) — Union Day.
  • May 21–22 — Eid el-Fitr (estimated).
  • December 25–26 — Christmas + Boxing Day.
