We would like to add new calendar model to Wikidata for supporting Hebrew dates.
Conversion from Hebrew dates to Georgrian is pretty straight forward.
Exception: Hebrew dates don't start in the midnight but in the sunset.
How to deal with it (in case we don't know the hour/minute/second) when converting to Georgian:
1. Most of the day is daylight so usually it can be ignored and get the correct date
2. To indicate it is not lossless conversion by changing the precision of converted dates?
(TODO: update the task description based on talks we had or should have in the #wikimedia-hackathon-2016 )
