One system for every part of shul life.
Built for the gabbai, the office, the treasurer and the Rav — and simple enough that every congregant finds what they need in seconds.
Congregants
Households, Hebrew names, lineage, yahrzeits and simchas. Import from a spreadsheet in minutes.
Minyan rules
“15 minutes before shkiya, rounded down.” Write it once; every day of the year is computed.
Zmanim
Magen Avraham or Gra, 8.5° or Rabbeinu Tam. Fourteen opinions, calculated for your coordinates.
Giving & dues
Funds, dedications, monthly gifts, household balances and tax receipts the moment a gift lands.
The Rabbi's desk
Divrei Torah with audio or video, published to the site and emailed to the kehilla in one step.
Announcements to everyone, members, or any group — with yahrzeit reminders that send themselves.
Classes & live
Registration, payment and low-latency live streaming, with a library of past shiurim.
Mikveh
Hours that follow tzeit through the year. Private appointments and a focused attendant view.
Website
A fast, accessible site at yourshul.chizku.com or your own domain. Never out of date.
Write the rule. Chizku does the math.
Times move with the sun every day. Describe each minyan the way your gabbai thinks about it and Chizku handles daylight saving, Rosh Chodesh, fasts, Yom Tov, Chol HaMoed and legal holidays — then publishes a weekly PDF and a calendar feed congregants subscribe to.
| Day | Shkiya | Minyan |
|---|---|---|
| Sunday 10/25 | 6:01 PM | 5:45 PM |
| Monday 10/26 | 5:59 PM | 5:40 PM |
| Tuesday 10/27 | 5:58 PM | 5:40 PM |
| Wednesday 10/28 | 5:57 PM | 5:40 PM |
| Thursday 10/29 | 5:55 PM | 5:40 PM |
Bring your processor. Every dollar goes to the shul.
Paste your keys into one form. Chizku checks them with the processor on the spot, encrypts them, and never sees a card number — donors type into the processor's own secure fields.

A website that is never out of date.
Times, Shabbat, the Rabbi's latest message, classes and events reach your site the moment they change. Start on a chizku.com address and connect your own domain whenever you're ready — HTTPS is automatic.
