Panchang for Singapore — 13 December 2026

Shukla Chaturthi tithi, Uttara Ashadha nakshatra · Sunday · (1.3521°, 103.8198°)

Dina Shuddhi (day purity): Partial (3/4)Vikram Samvat 2083 (Siddharthi)Shaka Samvat 1948Vrischika (Kartika)

A pañcāṅga is the day's five limbs — tithi, vāra, nakṣatra, yoga and karaṇa. All five come from the real positions of the Sun and Moon and change through the day, so they are reckoned from Singapore (1.3521°, 103.8198°)'s own sunrise — 06:57 AM here today rather than from a national average. Below are today's five with the time each ends, and then the day's auspicious and inauspicious windows.
