Aaj Ka Panchang.

On 30 September 2026 the tithi in London is Krishna Chaturthi, prevailing at sunrise and ending at 10:27 AM BST. The nakshatra is Krittika (pada 1) until 1:33 AM BST.

Rahu Kaal in London on 30 September 2026 runs 12:50 PM to 2:17 PM BST. Yamaganda (8:28 AM–9:55 AM) and Gulika (11:23 AM–12:50 PM) are also inauspicious — avoid starting new work in all three. They are computed from London's actual sunrise, not a fixed national table.

The universally auspicious Abhijit Muhurat runs 12:27 PM–1:13 PM BST. The day's cleanest choghadiya window is Laabha, 7:00 AM–8:28 AM BST. The full 16-slot choghadiya table marks every Amrit and Shubh slot through the day and night.

Tithis, nakshatras and yogas are moments in time, but Rahu Kaal, choghadiya and Abhijit are derived from local sunrise and sunset, so they shift with longitude and latitude. Bela computes each city from its own coordinates (51.5085°N, -0.1257°E) — never a national average.

Bela's engine scans all 16 choghadiya windows of the day for each activity and scores the best one by classical muhurta rules: Rahu Kaal, Yamaganda, Gulika, Durmuhurtam, Panchaka, nakshatra suitability, tithi and yoga. The 0–100 score is that window's strength — personal Tara Bala vs your birth star is an app feature.
