# Ritupatra: Bengali calendar and panjika, with no ads > Ritupatra is a Bengali calendar and panjika app for West Bengal: today’s Bengali date, tithi, puja and festival days, offline, with no ads and no account. Canonical: https://ritupatra.app/en/ Bengali version: https://ritupatra.app/ Last updated: 2026-10-28 Times: Kolkata, Indian Standard Time (UTC+05:30) ## In Bengal, the day begins at sunrise Ritupatra counts the same way: the tithi at sunrise, the Bengali date, the puja times, all by the sky over West Bengal. No ads, no internet needed, free. ### Today, in Kolkata - **Today**: 11 Kartik 1433, Wednesday, 28 October - **Tithi**: Krishna Tritiya until next day 1:07 am, then Krishna Chaturthi - **Next festival**: [Dhanteras](https://ritupatra.app/en/festivals/kali-puja-2026) in 9 days Updated Wednesday, 28 October 2026, 9:34 am ## One day, as Ritupatra counts it Today, from sunrise to night. Scroll and the sky moves on; every time here is Ritupatra’s own calculation for Kolkata. ### Sunrise, 5:39 am: The Sun is up, the day begins The tithi running at the moment of sunrise is the day’s tithi: Krishna Tritiya. The Bengali date changes at sunrise too, not at midnight. Today is 11 Kartik. ### The morning note, 7:00 am: One notification, only if you want it Today’s tithi and the next festival, in one note. It is made on your phone, not sent from a server, so it comes even with no signal. ### The tithi changes, next day 1:07 am: The tithi can change mid-day Today Krishna Tritiya ends at next day 1:07 am, then Krishna Chaturthi. Puja times follow this, so the app gives each tithi’s start and end to the minute. ### Sunset, 5:02 pm: Lamps at dusk As the Sun sets, the app’s sky changes colour too. On a festival day the Today screen dresses up, with a greeting card to send. Coming up: Kali Puja, in 11 days. ### Night, Moon 95%: The Moon as it is At sunrise today the Moon was 95% lit, waning. Ritupatra’s sky shows it at that size, and on the night of Kojagari an owl arrives and lamps float on the water. ## The days people wait for The pujas and festivals from today, by the rules of the West Bengal panjikas, counted by the Drik school. Each festival’s page gives the tithi times and the rule behind the day. - [Dhanteras](https://ritupatra.app/en/festivals/kali-puja-2026): Friday, 6 November · 20 Kartik · in 9 days - [Kali Puja](https://ritupatra.app/en/festivals/kali-puja-2026): Sunday, 8 November · 22 Kartik · in 11 days - [Dipaboli (Diwali)](https://ritupatra.app/en/festivals/kali-puja-2026): Sunday, 8 November · 22 Kartik · in 11 days - [Bhai Phonta](https://ritupatra.app/en/festivals/bhai-phonta-2026): Wednesday, 11 November · 25 Kartik · in 14 days - [Chhath Puja](https://ritupatra.app/en/festivals/chhath-puja-2026): Sunday, 15 November · 29 Kartik · in 18 days - [Jagaddhatri Puja](https://ritupatra.app/en/festivals/jagaddhatri-puja-2026): Thursday, 19 November · 3 Agrahayan · in 22 days - [Ras Purnima](https://ritupatra.app/en/festivals/ras-purnima-2026): Tuesday, 24 November · 8 Agrahayan · in 27 days - [Poush Sankranti](https://ritupatra.app/en/festivals/poush-sankranti-2027): Thursday, 14 January · 29 Poush · in 78 days ## The promise No ads.
