limited functions

The look of the app is great, but the functionalty is a bit limited.

When converting medieval dates, the conversion algorithm for H-> breaks down at the beginning of the Gregorian era, 1582. For dates before this, the read out is always 11, (null), -4714. For these dates, the conversion should be made to Julian dates. The algorithm is fairly simple and can be found online.

For the G-H conversions prior to the beginning of the Gregorian era, the app gives a Hijri date, but it is incorrect.

Hopefully, these minor bugs will be fixed in the next version.

Thanks for the app.
