Accurate Hebrew Dates for Meaningful Lifecycle Tracking

Convert secular dates to the Hebrew calendar with Tseis (nightfall) adjustment, ensuring your congregation's birthdays and yahrzeit memorial dates align with halachic dates.

Halachic Date Tracking Built for Synagogue Administration

In Jewish tradition, the halachic day begins at nightfall (Tseis HaKochavim), not midnight. This means an event occurring in the evening belongs to the following Hebrew date.

Makomly simplifies this with a clear administrative toggle: mark whether a birth or passing occurred before or after Tseis. The engine automatically computes the correct Hebrew date and keeps family records synchronized.
