My; chart has a series of English dates. I would like to feed  the English date and retrieve the corresponding Hebrew date.I need detailed guidance for this as I  do not have developer training with Excel.  

Sun 7/28 13 Sivan
Mon 7/29 14 Sivan
Tue 7/30 15 Sivan
Wed 7/31 16 Sivan

I would like to determine the date in Column C from B. 

My Excel chart has a series of dates that I would like to convert to their Hebrew counterpart. I would like detailed step by step guidance as to how to accomplish that goal. Thanks.
