Persian Calendar is for people who need the Persian calendar on their phone, alongside Gregorian and Islamic dates, and who prefer free software without ads. It is published by the Persian Calendar Project, costs nothing and is licensed under GPL-3.0-only. The package is com.byagowi.persiancalendar, and version 10.2.0 was updated on April 22, 2026.
Setting up version 10.2.0 on Android 6.0 or later
The download is 3.4 MB, so it installs quickly and takes little space. You need Android 6.0 or newer. The app first appeared on August 23, 2012, which makes it a long-running project.
After installing, check the language first. The app supports Dari, Kurdish, Azeri, Pashto, Arabic, Gilaki, English, Turkish, Japanese, Spanish, Chinese and French. Then look at the Athan player, which is optional, so you can leave it off if you only want dates.
Qibla compass, Athan and three calendar systems
The core is the Persian calendar, with support for Gregorian and Islamic calendars next to it. That lets you read the same day in more than one system without switching apps.
A compass for finding the Qibla is included, as is Athan support. The Athan player is optional. The app also works with TalkBack, Android's screen reader, which matters for blind and low-vision users.
When Fossify Calendar or Google Calendar fits better
Persian Calendar is a date reference with religious tools. It does not offer event sync or shared agendas, so look elsewhere if you need scheduling. Fossify Calendar and Google Calendar are alternatives, and Samsung Calendar suits Samsung phones.
For other needs, Hebrew Calendar covers a different calendar system. Period Calendar Period Tracker and jtx Board journals|notes|tasks serve tracking and notes, which this app does not cover.
