About

Pitru Calendar

Features
Read full description

Pitru Calendar is a Tamil-first panchanga, designed for families who keep their ancestors close. Track the daily tithi, Tamil month and day, nakshatra, and paksha with names you already know — வளர்பிறை பிரதமை, தை 1, கார்த்திகை — the way Pambu Panchangam and Arcot Panchangam print them. Every day's panchanga is computed from the Vakya tradition; Vakya-vs-Drik differences are documented openly. For Iyer and Iyengar families, the app makes ancestor srardham observances easy to track. Add each ancestor once — name, gothram, the tithi and Tamil month of their passing — and the calendar surfaces every annual srardham, Mahalaya tarpanam, and aabdikam date going forward. Festivals included for Tamil Nadu and pan-India Hindu observance: Thai Pongal, Aadi Perukku, Aavani Avittam, Vinayagar Chaturthi, Mahalaya Amavasai, Vijayadashami, Karthigai Deepam, Vaikunta Ekadashi, Maasi Magam, Panguni Uthiram, and the full Ekadashi / Pradosham / Sankashti Chaturthi cycle. Privacy is the foundation: • Everything stays on your device. No analytics. No third-party tracking. No SDK. • Ancestor names never leave the app — Siri reads only dates, never names. • Backups are encrypted with your passphrase using AES-GCM-256. • iCloud sync (optional) uses Apple's private database with end-to-end encryption. Tamil VoiceOver is supported with proper language tagging. Apple Watch and Lock Screen widgets show today's panchanga at a glance. Siri shortcuts: "What's today's panchanga?" "When is the next srardham?" The app is bilingual: Tamil names are primary; English alternates are always present.
