B4A Library DateConvert library

Here is a library to translate Gregorian dates to Hebrew dates and vice versa, from year 2 and on!
Result can be numerical or Hebrew.

Edit: Version 1.1 includes another method isLeapH which returns if the Hebrew year is a Leap year.
Also correction of a bug which appears in devices but not in emulator !

Edit: ver. 1.2 includes two more methods: IsLeapG to find if a Gregorian year is a leap year, and HebMonthLength which returns the length of a Hebrew month per specified Hmonth and Hyear.
Edit: ver 1.2.2 - found and corrected one day shift in GregToHeb methods.

ver 1.2.1 - found and corrected one day shift in GregToHeb.
1.2.2 for the other GregToHeb method.
Took a while to see the problem as it appears differently on different devices/emulators.

hi david
there is a problem with the calculations, check this month :2/2014 (one day shift)

 

[derez]

I have the correct days : today 16/2 I get 16/6/5774 (which is correct !)

thanx david, but i dont think i can run it on b4i. maybe if you would share the class it could be done
anyway i found this that does the job and it is a class running on b4x: https://www.b4x.com/android/forum/threads/hebrew-calendar.92548/
