Every Jew needs access to a good Jewish calendar. There is a prodigy somewhere who can keep track of all the ins and outs of the nineteen-year cycle of the Jewish year, but the rest of us need a little help.
My favorite Jewish calendar is an online calendar: www.hebcal.com. (The builders of the calendar say it’s pronounced HEEB-kal dot com.) It is free and fabulous: their description:
We offer a powerful custom Jewish calendar tool that lets you generate a list of Jewish holidays for any year (past, present or future). Also available are a Hebrew date converter, Shabbat candle lighting times and Torah readings(both full kriyah and triennial system), and a page to look up yahrzeits, birthdays and anniversaries.— “About Hebcal”
If I could have access to only one site on the entire Internet, this one would be it!
