Features

  • Three calendars side by side

    Solar Hijri, Gregorian and Iran's lunar Hijri on every day. The month grid leads with Solar Hijri, Gregorian or a Zoroastrian calendar, with the others small under each date.

  • Accurate to the day

    Each Persian year starts the way Iran's Calendar Center starts it, from the March equinox against true noon on Iran's meridian, not from a leap-year formula. Lunar months follow Iran's own sighting; forecast months are marked ≈.

  • Four Zoroastrian calendars

    Shahenshahi, Kadmi, Parsi Fasli and Iranian (Bastani), with the roj and mah of each day, its yazata, and the gahambars and other observances.

  • Sunrise, sunset and the gahs

    The five gahs worked out from your place, by the Parsi clock or true solar noon, with the gah now and the time left. Pick a city or use your location.

  • Holidays and occasions

    Iran's official holidays, national, religious and international days, the ancient Iranian festivals and Zoroastrian observances. Show the groups you want and search them all.

  • Convert any date

    Spin in a date in any of the seven calendars and see it in all the others, then jump to it on the calendar.

  • Count down to Nowruz

    Through Esfand, a countdown runs to the exact moment of the tahvil, in Tehran time and yours.

  • Widgets

    Today, Gah and Coming up widgets for the Home Screen and Lock Screen, in small, medium and large.

  • Apple Watch

    Today's dates, the gah now and what's coming up on the watch, plus complications for your watch face.

  • Reminders

    Optional reminders for occasions (the day before too), each morning's roj and every gah. They're scheduled on the device.

  • Persian or English

    Persian, right to left with Persian digits, is the default; switch to English in Settings. Light, dark or system theme.

  • Free and private

    No accounts, ads, analytics or tracking, and nothing to buy. The app works offline, and your settings stay on your devices.
