Welcome to Persian Calendar -
a friendly, accurate Persian (Shamsi) and Gregorian calendar that’s always with you and keeps your days, months, and years nicely organized.

With Persian Calendar you can follow the 1404 and 1405 Persian years alongside the matching 2026–2027 Gregorian years, so you never get confused between the two systems again. It’s made for people who live their daily life with the Persian calendar but still need the Gregorian one for work, travel and international communication.

Use it on all your Android devices – phone, tablet, smartwatch and Android TV – and keep the same clear view of today, tomorrow and the months ahead everywhere.

- Iranians living abroad who constantly convert dates between Shamsi and Gregorian

📅 Dual calendar: Shamsi & Gregorian

Stay on top of both calendars at the same time:

You can:

- See today’s date in both Shamsi and Gregorian formats
