August 2026 Panchang Calendar — Kolkata
Every tithi and nakshatra below is the one in force at Kolkata's own sunrise on that date — Kolikata sits at 88.36°E, so a day can carry a different tithi here than in a calendar computed for another meridian when a boundary falls near dawn. The lunar month is labelled by the purnimanta convention this city uses.
| Measure | Value |
|---|---|
| Lunar months spanned | Shravana–Bhadrapada |
| Earliest sunrise | 05:08 |
| Latest sunrise | 05:19 |
| Longest day | 790 minutes |
| Shortest day | 756 minutes |
| Ekadashi days | 2 |
| Purnima / Amavasya | 1 / 1 |
| Mornings whose tithi differs from New Delhi | 0 |
Sunrise in Kolkata moves from 05:08 on the 1st to 05:19 on the 31st, and sunset from 18:18 to 17:55 — the day shortens by 34 minutes across August, which drags every kaal window and every Choghadiya slot with it.
On none of the 31 mornings this month does the tithi at Kolkata's sunrise differ from the one at New Delhi's — every boundary this month happens to fall clear of both dawns.
The two times under each date are that morning's sunrise at Kolkata and the start of that day's Rahu Kaal, which is the eighth of real daylight assigned to Rahu on that weekday. Both move with the city, not just with the date: they are what a calendar computed for another meridian gets wrong even on the days it agrees about the tithi.
How far the nearest other sky is
Of the other cities computed on this site, the closest to Kolkata by sunrise is Bhubaneswar, 365 km away, where sunrise runs up to 14.9 minutes from this one. Over the 365 mornings behind this calendar the tithi differs on 3 of them — a boundary falling between the two dawns. That is a small number and it is the whole argument: on those mornings a calendar reprinted from Bhubaneswar would be wrong here, and there is no way to know which mornings without computing both.
Everything on this page is read at Kolkata's own sunrise, from its own coordinates — 22.57°N 88.36°E — so it is not the nearest city's calendar with a name changed on it.
Observances in August 2026
| Date | Observance | Tithi it is fixed to | What the day is |
|---|---|---|---|
| 9 August | Kamika Ekadashi | Shravana Krishna Ekadashi | The first ekadashi of the Kanwar month; the walkers time their arrival by it. |
| 12 August | Hariyali Amavasya | Shravana Krishna Amavasya | The green new moon of the monsoon; tree-planting and Yamuna bathing across Braj. |
| 15 August | Hariyali Teej | Shravana Shukla Tritiya | The Shravan third; Jaipur's Teej procession leaves the City Palace on it. |
| 17 August | Nag Panchami | Shravana Shukla Panchami | The serpent fifth; Nagpur's Nagoba temple keeps the district's largest queue for it. |
| 23 August | Putrada Ekadashi | Shravana Shukla Ekadashi | Pavitropana ekadashi, kept in Shravan's bright fortnight. |
| 28 August | Raksha Bandhan | Shravana Shukla Purnima | Shravan Purnima; the thread is tied outside the Bhadra karana, which this site computes and flags. |
| 31 August | Kajari Teej | Bhadrapada Krishna Tritiya | The dark-fortnight teej of eastern UP and Bundelkhand, a fortnight after Hariyali Teej. |
Why the month is named what it is here
Bengal dates its civil year by a solar calendar, the Bangabda, whose months turn with the Sun's sign and whose new year is Poila Boishakh in April. Pujas, however, are fixed by tithi, and it is the tithi that this page computes. The lunar month label used here follows the purnimanta convention; a Bengali panjika will express the same night through its own solar date, so expect the day names to agree and the month names not to.
How a festival lands on a date
None of the dates above is stored. Each observance is held here as the rule that defines it — a lunar month, a fortnight and a tithi — and resolved against the computed panchang for Kolkata each time this calendar is rebuilt, which is why the same festival moves through the Gregorian year and why two adjacent cities can differ by a day. The lunar month name follows the purnimanta reckoning; the intercalary adhika masa, which repeats a month name roughly every thirty-two months, is detected and its festivals are attributed to the regular month rather than the leap one.
A day is marked by the tithi standing at sunrise. Observances that are settled at another moment — Janmashtami at midnight, Diwali at pradosh, Ahoi Ashtami at starrise — can therefore be announced by a temple one day either side of the marker here, and the table above says so where it applies. Solar festivals such as Makar Sankranti are keyed to the Sun's ingress instead, which is why they barely move.
