Ucham: Tamil Panchangam

உச்சம் · Ucham is the daily Tamil calendar (panchangam) for your city — tithi, nakshatram, Rahu Kalam, festivals, muhurtham and temple calendars, calculated on your own phone. Wherever you live, Ucham computes the day from your city's actual sunrise — not from a printed table made for Chennai or Colombo — in both the Thirukanitham and Jaffna Vaakiyam traditions. DAILY PANCHANGAM • Tithi, nakshatram, yogam and karanam for any day and any city • Two authentic systems: Thirukanitham (modern astronomical calculation) and Vaakiyam — the traditional Jaffna Sūrya-Siddhānta method • Sunrise, sunset and Rahu Kalam, so you can plan around the right times FESTIVALS & VIRATHAM • Fasting days and festivals — Chaturthi, Sashti, Pournami, Amavasai, Ekadasi and more • Clear two-day labelling where a viratham spans two days MUHURTHAM • Suitable days for important events, with good windows shown and Rahu Kalam avoided • Rule-based guidance to discuss with your family astrologer TEMPLES • Mahotsavam calendars for 174 temples across Sri Lanka, Tamil Nadu and the diaspora • Kodi, Ther and Theertham dates • Filter by region and pilgrimage circuit JATHAGAM • Traditional birth-chart calculation — South Indian rasi chart, planet positions, nakshatram and padam • Houses, planetary positions, kolcharam (current transits) and the Vimshottari dasa timeline • Marriage compatibility (porutham) between two charts, with a shareable summary • Your birth details stay on your device — nothing is uploaded PRIVACY FIRST Ucham keeps your personal details on your own phone.
