Store description excerpt

Aathan Tamil Calendar — Panchangam, Rasi Palan, Muhurtham & Peyarchi, all calculated with the same astronomical precision from 1950 to 2100. WHY AATHAN IS DIFFERENT Most Tamil calendar apps mix methods — a fixed almanac (Vakiya Panchangam) for the daily calendar and a separate calculation method for horoscopes. Aathan uses one consistent engine — Swiss Ephemeris, the same precision astronomy software trusted by serious astrological research — for every single day from 1950 through 2100. One method, no inconsistency, no century-old accumulated drift. DAILY PANCHANGAM • Thithi, Natchathiram, Yogam, Karanam — with exact start and end times • Nalla Neram, Rahu Kalam, Yamagandam, Kuligai, Gowri Panchangam • Amavasai, Pournami, Ekadasi, Pradosham, Sashti, Chaturthi, Ashtami, Navami • Chandrashtamam and sun/moon nakshatra tracking • Choose Madhyahna (midday) or Udaya (sunrise) tithi convention — your call MUHURTHAM FINDER — BUILT ON REAL RULES, NOT A STATIC LIST Other apps show a plain list of "auspicious days." Aathan computes them from the actual classical exclusion rules: • Rikta tithi exclusion (Chaturthi/Navami/Chaturdashi) • Guru Asta (Jupiter combustion) — calculated from real planetary positions • Aadi and Margazhi masam exclusions • Tuesday/Saturday weekday exclusions • Separate categories: Marriage, House-Warming, Business Opening, Vehicle Purchase, and Farming — each with its own correct rule set • Valarpirai/Theipirai (waxing/waning) shown alongside every muhurtham date RASI PALAN & PEYARCHI • Daily, weekly, and monthly Rasi Palan for all 12 signs • Guru Peyarchi and Sani Peyarchi (Jupiter & Saturn transit) tracking • 27-nakshatra personalization for transit predictions — most apps only go as deep as your rasi; Aathan goes to your birth star FESTIVALS, HOLIDAYS & FASTING • Full Hindu festival and government holiday calendar • Region-aware holidays for India, Sri Lanka, Singapore, Malaysia, UAE, USA, UK, Canada, Australia • Fasting and vrat reminders (Ekadasi, Pradosham, and more) WORKS OFFLINE Full panchangam data is bundled on your device and syncs automatically when online — no waiting, no data charges to check tomorrow's tithi. YOUR PRIVACY, RESPECTED • No login or account required • No personal information collected — ever • Your notes and reminders stay on your device • Full privacy policy available in-app Available in Tamil, English, and Tanglish (Tamil-in-English-script) — switch anytime in Settings. Aathan Tamil Calendar — the Panchangam that shows its work.
