Ji Calendar is a state-of-the-art, educationally rich, imaginative and enriching series of modules to teach everything that a child needs to know about the Jewish calendar. The app is divided into a classroom tool and an addictive game for students. Students can design their own ‘space kid’ who will accompany them on their entire journey through the Jewish Calendar.



Simulations of the astronomy involved with days, months and years. Each simulation displays a window representing what you would see on earth, together with a working 3D model of the solar system, that students and teachers can manipulate to create certain circumstances. 

Jewish Calendar
At the heart of the product is a calendar tool, which can be used as a classroom tool. Teachers are encouraged to use this tool every day, to discuss today, this month, and this year. The tool demonstrates clearly the overlay of the secular and Jewish calendars. If you have enabled your location settings on your device, then the time shown in the calendar for the zmanim, or times of the Jewish day, will be accurate for your location.

Time Challenge
Students will find this game addictive, while being immersed in travelling through time. Major concepts are reinforced, and earning ‘powerups’ involves completing quests in the simulations. Students will run through a Jewish day, learning zmanim, through the Jewish week, learning the connection between Creation and the days of the week culminating in Shabbat, through the month, connecting moon phases with the date in the lunar cycle, and through the year, connecting seasons with Jewish months in Israel.

Ji Tap Lessons on the Calendar
The educational content is reinforced with highly interactive educational lessons, built by Ji experts, in Ji Tap. These games are accessible from within the app.
