About Mawlidi

Mawlidi is an independent Arabic project offering precise tools for Hijri date and lunar age calculation, alongside knowledge content about the calendar, astronomy and civilisation. Everything here is free, with no subscription and no sign-up.

What we offer

Nine tools that run entirely inside your browser: a Hijri–Gregorian date converter, a printable full-year Hijri calendar, an age calculator across both calendars, a countdown to Islamic occasions, the Moon phase on your birth date, a shareable birthday card, the twenty-eight lunar mansions, and the Sun’s position in the zodiac. Alongside them, a library of articles on the calendar, humanity and civilisation.

Our charter

This is a site of calculation, not divination. We present verifiable astronomical facts: the Moon’s position, its phase, the corresponding date. We describe no one’s character and predict no one’s future.

How we calculate

We use the tabular Hijri calendar (the Kuwaiti algorithm), which is arithmetic rather than observational. In many countries the month begins with a crescent sighting and may differ by one day. Every tool therefore carries an explicit note: our calculation is a precise estimate, not a religious announcement, and the relevant authority in your country is the reference.

Astronomy tools

Moon phases, lunar mansions and solar position are computed with an abridged Meeus algorithm, verified by fifty automated tests including documented new and full moon instants and each mansion falling on its actual star.

Who is behind it

Artist Altayeb Amer. Mawlidi is part of a network of sites offering free services: image tools, printable worksheets, a digital Quran, and an art gallery.
