Browse to any year in the future, and read all the dates you need. ** Cross-calendar date conversions (Jewish - Gregorian) ** So you can quickly look up any date. Need to know what was the Jewish date for June 5, 1931? CalJ helps you in just a few clicks. ** Zmanim (times) of the daily prayers ** No matter the date or location anywhere in the world: check beforehand from what time it is permitted to put Tefilin, or until what time you can daven Mincha, when to burn the Chametz, etc. ** Birkat haMazon, Siddur tefilat Arvit and Min'cha ** It is so easy to pull out one's smartphone to daven Min'cha, or to recite Birkat haMazon after a meal! And for yet more comfort, CalJ highlights the special paragraphs for Chanuka, or Rosh Chodesh, etc. Never miss them again! ** Rosh Chodesh Reminders ** In order to light a candle, and not forget the special mentions in the Tefila. Then, a few days later, CalJ offers to show the text for Birkat haLevana. ** Birthdays and Memorials (Yahrzeit) ** Record the date of birth of your relatives, and the Azcara date of your departed : CalJ will make the anniversaries appear in your calendar each year, with an optional alert.
