Location-Aware Hebrew Date & Yahrzeit Calculations
Prevent conversion mistakes. Automatically convert Gregorian dates to Hebrew dates based on physical coordinates and sunset times.
The Challenge of Sunset Conversions
In Jewish tradition, the day starts at sunset (Tseis HaKochavim), not midnight. This makes tracking yahrzeits (anniversaries of deaths), births, and bar/bat mitzvahs complicated. If a death occurs on a Tuesday night after sunset, the Hebrew Yahrzeit is actually recorded as Wednesday.
Makomly solves this by using geographic coordinates for your synagogue. When entering dates, administrators select a simple toggle: **"Occurred After Sunset (Tseis)?"**. The database automatically calculates the exact local sunset for that date and location, converting the Gregorian date to the correct Hebrew day.

Plaque Assignments & Aliyah Tracking
Once calculated, Yahrzeits are linked to specific memorial plaques inside the sanctuary. Makomly alerts administrators when a plaque needs light bulbs turned on, automatically updates weekly service bulletin templates with names, and prints scheduling sheets for Aliyahs (Torah honors).
