Jewish Holiday dates(repost)

This project requires a Jewish person familiar with the relative importance of of various important dates observed by Jewish people. My software already does (amongst other things), speaks a phrase each day to tell you something interesting about the current day. For instance, for Christans it tells you "Tonight is Christmas Eve", "Merry Christmas", "Happy Easter", "Today is Good Friday", etc. My software is for humor and hearing newsfeeds, weather, and web content, and is not meant for serious religous messages or comprehensive religious coverage. I just want to give Jews (or other religions) the option to turn off Christian dates and hear Jewish (or other religions') dates instead. Using a resource like [[login to view URL]][1], or other sources like wikipedia, the goal of this project is for the coder to provide a pre-calculated list of dates for the most important holiday/observance days. from 2011 to 2030. For example, Passover: 2011: April 18 2012: April 6 2013: March 25 etc up to year 2030. Provide a short speakable phrase in English, for each observance day. suitable to be spoken in the morning when a user typically turns on their computer, to tell them about the special Day. For example Passover: "Tonight after sunset, Passover begins." Hanukkah: "Happy Hanukkah". (if there's a better phrase then "Happy Hanukkah", I'll use it.) See, just a short phrase, not explaining the meaning of it or what people do on that day. Just a quick reminder that today is a certain day. ## Deliverables As part of the work, explain to me, which days are important and which days are only of interest to a subset of Jews. I only want the important days done. Don't work on the lesser days that only interest the subset. An equivalent example, for Christians I'm only using Christmas Eve, Christmas Day, Good Friday, Easter Monday. You don't need to- and probably shouldn't- explain everything in advance prior to bidding. Finding the dates is not as easy as it seems. [[login to view URL]][2] only provides exact dates up to 2020, but I need dates up to 2030. So some research finding a better source or a formula might be needed.
