Sabbath Clock
CHOZEN DIGITAL
Know the hour. Keep the day.
The Sabbath Clock is a free web app from ChoZen Unlimited that shows the exact moment the Sabbath begins and ends in your city — computed from the sun itself and matched against the U.S. Naval Observatory to the minute.
Houses reckon the evening differently, so the clock gives you four ways — sunset, first stars, full dark, and deep dark — and imposes none of them. Your house, your reckoning. It remembers your city and your choice.
No account. No ads. No tracking. No price.
Your times, every Friday morning
Sign up inside the app and one email arrives each Friday morning with your city’s exact times for that evening — and it is never sent on the Sabbath, in any timezone on earth.
“…from even unto even, shall ye celebrate your sabbath.”
— Leviticus 23:32, King James Version
