How is a date written in Swahili?

A Swahili date reads as tarehe followed by the day number, then the month, then mwaka and the year, for example tarehe sita Juni mwaka elfu mbili na ishirini na sita. The weekday name may be placed in front for a fuller form.

Writing a date out in full Swahili (Kiswahili) combines the word tarehe (“date”), the spelled-out day, the month name, and the spelled-out year. This tool takes any calendar date and produces that prose, including the correct weekday name.

How it works

The date is parsed into year, month, and day and validated so impossible dates are rejected. The weekday is computed from the date itself and mapped to its Swahili name (Jumatatu through Jumapili). The month maps to the standard Swahili Gregorian names (Januari to Desemba).

The day and year are converted to Swahili cardinal numbers using the same kumi / mia / elfu system as written numbers. The pieces are then assembled into a full form with the weekday and a compact tarehe form without it.

Example

The date 2026-06-06 renders as:

Ijumaa, tarehe sita Juni mwaka elfu mbili na ishirini na sita

or, in the compact form:

tarehe sita Juni elfu mbili na ishirini na sita

Notes

  • Swahili uses cardinal numbers for dates, so the 6th is sita, not an ordinal.
  • The weekday is calculated, so it is always correct for the date you choose.
  • Month names follow the international set used across East African Swahili media and official writing.
