Hello friends!

You have a amazing web site. Very usefull!

Im a brazilian researcher and can you help me with hebrew calendar of 3755/3756 (5,6 b.C.). I would to know the holydays in both calendars, specially Pessach, Parashat Bamidbar and Shavuot.

May you help me?

Best regards

Are there any plans for developing an international API for Shabbat times, such as a WordPress widget?

Please permit zero and negative Gregorian years so the calculator can function as an "astronomical" Gregorian-to-Jewish calendar converter.  Astronomy requires contiguous years and although 1 BC jumps to 1 AD, for the purpose of astronomy, 1 BC is year 0, 2 BC is year -1, etc.

By the way, thank you for not including the 10-day Gregorian transition since your converter works as an "astronomical" Gregorian calendar converter for Gregorian dates before the transition (not interested in Julian dates in history, just Gregorian dates for astronomy).  We just need the converter to accept year 0 and negative years.  Thanks!

The links off the calendar to Kinnim 23-25 are not functional.
