If you use Hindu Calendar for finding out when it is Purnima and when it is Amavasya or which Hindu Month it is, there is a Hindu calendar for iPad available. This calendar is developed by ABCOM which combines both Hindi and English Calendar together for year 2011. There is a Marathi Version of this calendar but that costs 1.99 USD.
Features of Hindu Calendar :
- Hindu Holidays and Festivals.
- Hindu Months like Paush, Falgun, Chaitra and so on.
- The festivals are nicely iconed with images which is very catchy.
- You can change the background of calendar.
- Works nicely both in Potrait and Landscape mode.
However there are two drawbacks. One it is only for the year 2011, so you will have to wait for an update next year and secondly the navigation is poor, you need to flip each month to go back and forth. Download from iTunes.
