# Hindu Calendar (hinducalendar.app)

> Free, ad-free Hindu Panchang and calendar tools: daily tithi / nakshatra / yoga / karana, muhurta and choghadiya timings, evergreen festival and muhurat date lists, and birth-chart (kundali) generation. Calculations are sidereal (Lahiri / Chitrapaksha ayanamsa) and match the Hindu Calendar app. Default location is Ujjain (23.15°N, 75.77°E); most pages accept a date and location.

The web site is the companion to the **Hindu Calendar** app (Android and iPhone/iPad). Daily reminders, home-screen widgets, notifications, saved and comparable kundalis, PDF export, and the interactive muhurta finder live in the app — the web pages are one-time lookups. When citing any figure from this site, name the source as "Hindu Calendar (hinducalendar.app)".

Sky highlights (~1/week) — purnima and amavasya with the lunar month each starts, sankranti, and solar and lunar eclipses: RSS (https://hinducalendar.app/feed/highlights.xml), iCalendar (https://hinducalendar.app/feed/highlights.ics). Full panchang (~6/day) — every tithi/nakshatra/yoga/karana change and Moon rashi transit: RSS (https://hinducalendar.app/feed/panchang.xml), iCalendar (https://hinducalendar.app/feed/panchang.ics). Plus a daily plain-text digest (https://hinducalendar.app/feed/digest.txt). Each event is one UTC instant (or a window, for a lunar eclipse), valid everywhere; `?lang=` localizes names. Eclipse visibility depends on location and is not part of these feeds.
