Emails your list when the Kiddush Levana window opens (and before it closes) — molad math done for you.
A daily cron that emails a subscriber list when the window to say Kiddush Levana opens each month, with an optional “closing soon” reminder. The window is computed from the molad via the free Hebcal API — opening 3 or 7 days after the molad (your minhag) and closing about 14 days, 18 hours after it. Manage recipients and settings from a password-protected admin page. It reports the window only; say the bracha at night under open sky when you can see the moon, and follow your minhag and rav (e.g. after Tisha b-Av in Av, after Yom Kippur in Tishrei). Finish setup by opening the app URL with ?setup=1.
