CalJ Jewish Calendar

About this app

Cal-J is a Jewish calendar app featuring:


** Shabbat Times **
For any city of your choice. You can also register several locations in order to prepare for traveling or to read the Shabbat times of your relatives around the world.


** Dates of Holidays, for any year **
Cal-J is a perpetual calendar: no need to wait for next year's edition in order to prepare your vacations right now. 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.

Ratings and reviews

I have a visual impairment. The "blind in one eye and can't see out the other" is true for me. And this is the absolutely best Jewish calendar that I have found. There isn't any fiddling with the settings so that I may hope see. Everything is clear and easy to read. Very precise but still simple enough for almost anyone to use. Thank you so much for making a wonderful product!!

Suddenly the app requires (!!!!, for what reason???) to know my location, which has been refused by my android to almost all apps. So when opening the app, it doesnt let me continue and gets stuck on the screen "This app requires to know your location, press OK". When pressing OK it keeps repeating itself (as blocked in android by default) and ends up in blocking my screen. I've used this app in the past, but this change and forced Location and blocking my android is a no-go.... Will search on

Very good app...has been getting better...I usually don't give 5 stars or comment because I have been burned by apps that were great and then like the Titanic sank. The best thing about this app is if you do have problems or suggestions they do listen, and will answer. Hard to believe this is made as a hobby, because it is so well made.
