From Ahmad Alavi:
The Persian Calendar Converter converts dates between the Iranian and Gregorian calendars.
- The application starts with today's date highlighted. - Turn any of the six wheels and the other wheels adjust to highlight the corresponding dates. - If the highlighted dates are today's date, they are displayed in blue. - The weekday of the highlighted date is shown at the bottom of the view. - Tap on the bar showing the weekday to toggle between Persian and English text. This option only works in devices with OS 3.0 or higher. - Shake the device to highlight today's date.
