Afghan Calendar Converter is a basic yet useful calendar converter available for iPhone users. This app allows you to easily convert dates between the Hijri Qamari (AH), Hijri Shamsi (SH), and Gregorian calendars. It also provides the corresponding day of the week for the selected date. Additionally, with a simple click on the "Today" button, you can instantly view the current date in all three calendar systems.

Please note that due to the complexity of date conversion methods and algorithms used for interchanging between these calendars, absolute accuracy in conversions may not always be guaranteed. For more detailed information regarding the conversion processes, users can refer to the info tab within the app.
