Zoro Cal

Track sacred Zoroastrian festivals, Gah periods, and daily observances across Shenshai, Kadmi, and Fasli calendars — all in one app.

Zoro Cal — Your complete Zoroastrian calendar companion.

Zoro Cal bridges ancient tradition with modern technology, helping the global Zoroastrian community follow their sacred calendar with ease.

THREE CALENDAR SYSTEMS IN ONE View dates simultaneously across all three Zoroastrian calendar traditions: • Shenshai — New Year on August 15 • Kadmi — One month ahead of Shenshai • Fasli — Vernal equinox-aligned, with leap day every 4 years All displayed alongside the Gregorian calendar with Yazdegerdi era (Y.Z.) dates.

DAILY GAH PERIODS & SACRED TIME Track all 6 daily Gah periods — Havan, Rapithwin, Uziran, Aiwisruthrem, and Ushahin — calculated from actual sunrise and sunset times at your location. Know the sacred time of day, every day.

SMART DAILY NOTIFICATIONS Start each day knowing your Roj, Mah, and any upcoming festivals. Notifications are delivered at sunrise (or your preferred time) with the full day's Zoroastrian information.

FULL FESTIVAL CALENDAR Comes pre-loaded with 50+ Zoroastrian observances including Nowruz, all six Gahambar celebrations, Gatha days, and more — calculated accurately for whichever calendar system you follow.

PERSONAL EVENTS Create and manage your own events anchored to either Gregorian or Zoroastrian dates, with recurrence support (weekly, monthly, custom). Import and export events via CSV.

CUSTOMIZABLE ROJ & MAH NAMES Edit all 30 Roj (day) names and 12 Mah (month) names to match your community's preferred spelling or transliteration.

FOUR CALENDAR VIEWS • Daily — Full details with events, Gah timeline, moon phase • Monthly — Grid overview • Yearly — Year-at-a-glance with carousel • Monthly Overview — Scrollable 12-month planning view

PRIVACY FIRST All your data stays on your device. No accounts required. No data collected or transmitted. Location is used only to calculate local sunrise times and is never shared.
