Whole month
How it is calculated, and the check against the panjika
Sunrise and sunset. The panjika uses the moment the centre of the sun is on the horizon, with no allowance for refraction (its table says “মধ্যবিন্দু”; for the upper limb, subtract 3 m 30 s from sunrise and add it to sunset). This is about 4 minutes later than the sunrise a weather app shows, and this page uses the panjika’s definition.
Eight parts. The day (sunrise → sunset) is divided into 8 equal parts (অর্ধপ্রহর). So is the night (sunset → the next sunrise). Each weekday has fixed parts that are inauspicious:
| Day | Bārabelā (parts of the day) | Kālarātri (parts of the night) |
|---|---|---|
| রবি · Sun | 4, 5 | 6 |
| সোম · Mon | 2, 7 | 4 |
| মঙ্গল · Tue | 2, 6 | 2 |
| বুধ · Wed | 3, 5 | 7 |
| বৃহস্পতি · Thu | 7, 8 | 5 |
| শুক্র · Fri | 3, 4 | 3 |
| শনি · Sat | 1, 6, 8 | 1, 8 |
A Hindu day runs from sunrise to sunrise, so the kālarātri of, say, Saturday includes the small hours of Sunday morning on the calendar.
Amṛtayoga and māhendrayoga (auspicious) are counted in muhūrtas: the day is divided into 15 equal muhūrtas, and so is the night, and each weekday has fixed muhūrtas. The panjika uses one table in dakṣiṇāyana (the months Śrāvaṇ–Pauṣ) and another in uttarāyaṇa (Māgh–Āṣāḍh). The tables were recovered from the panjika itself: 80 of 91 days of Āṣāḍh, Āśvin and Pauṣ 1433 follow them exactly, the rest differ by a misprint, and 867 of the 892 printed boundaries are reproduced within ±2 minutes. The uttarāyaṇa table has so far been checked on Āṣāḍh only.
Times are calculated for the place itself, with no fixed correction added to the Kolkata times. India is shown in IST; Bangladesh in Bangladesh Standard Time, which is 30 min ahead of IST. Centres abroad are shown in their own local time (with daylight saving where it applies).
Places. Every branch centre and sub-centre of the Ramakrishna Math and Ramakrishna Mission listed at belurmath.org/branch-centres (327 entries, as of 1 May 2026), at the position of its pin on the Math’s own centre map; plus 19 further locations on that map (Belur Math headquarters, retreats, city campuses). 11 centres without a pin were placed from their address and are marked “approx.” (within a few km — a few seconds of sunrise). Towns, districts and Bangladesh upazilas: GeoNames (CC-BY 4.0). A town position is its centre; 1 km east–west changes sunrise by about 4 s.
Check against the panjika — Viśuddha Siddhānta Panjikā 1433, Kolkata: Āṣāḍh (16 Jun – 17 Jul 2026), Āśvin (18 Sep – 17 Oct 2026) and Pauṣ (17 Dec 2026 – 14 Jan 2027), i.e. midsummer, equinox and midwinter. The page recomputes every printed sunrise, sunset and every boundary of bārabelā and kālarātri:
