How Naksham Computes This Calendar

Naksham reads each tithi from your local sunrise.[2] This is the Suryodaya Tithi (sunrise-anchored tithi) rule. Drik Panchang and the official Rashtriya Panchang both follow it.[3] We use the NOAA solar position model for sunrise and sunset. Output is accurate within 1 to 2 minutes for India locations. We use Lahiri ayanamsa (sidereal correction) for sky positions. Festival rules use Chandra masa (lunar month).[1] By default we count it from the previous Amavasya, the Amanta system used across South and West India. Diwali, the Sawan vrats, and a few other observances instead follow the Purnimanta month, the North Indian count from one full moon to the next. The two systems agree through Shukla Paksha (waxing fortnight) and split by a month through Krishna Paksha (waning fortnight), exactly where these fall, so Naksham matches each festival to the month name it is actually published under. Naksham detects Adhika Masa (extra lunar month) on its own. So festivals stay in the right Vedic month.[4]

Footnotes

  1. [1] Surya Siddhanta (8th century CE), Chapter 2: Madhyamadhikara. The classical Sanskrit text on Hindu astronomy. Defines tithi as 12 degrees of Sun-Moon elongation.
  2. [2] Brihat Parashara Hora Shastra (BPHS), Chapter 24: Yoga Karaka Adhyaya. Sage Parashara's foundational text. Establishes the sunrise-anchored Vedic day (Suryodaya Tithi).
  3. [3] Drik Panchang convention and Rashtriya Panchang (Government of India, 1957). The official Indian National Calendar reformed by the Calendar Reform Committee under Meghnad Saha. Sets the standard for sunrise-anchored tithi computation.
  4. [4] Brihat Parashara Hora Shastra (BPHS), Chapter 86: Festival Determination. Defines festival anchoring by Tithi plus Chandra masa. Adhika Masa rules from the same source. Cross-referenced with Wikipedia: Hindu Calendar.

Frequently Asked Questions

What does this monthly Tithi Calendar show?+

Are the Tithi dates accurate for my city?+
Naksham gives accurate output within 1 to 2 minutes for India locations. We use the NOAA solar position model and Lahiri ayanamsa (sidereal correction). We anchor each tithi to your local sunrise. This is the Suryodaya Tithi rule, per Drik Panchang and Rashtriya Panchang convention. Tithi, Nakshatra, Yoga, and Karana names stay the same across India. Sunrise and sunset shift with your city. Set your city in the location box for the best output.
What festivals are shown in this calendar?+
Naksham marks Hindu festivals, Ekadashi vrats, Purnima, Amavasya, and other key Tithi-based days. Festivals follow a Tithi plus Chandra masa (lunar month) rule. Each festival is colour-coded. Saffron is for major festivals. Green is for Ekadashi and vrats. Gold is for Purnima.
Which festivals does Naksham auto-detect?+
The list covers Vasant Panchami, Maha Shivaratri, Holi, Ram Navami, Akshaya Tritiya, Vat Savitri, Guru Purnima, Raksha Bandhan, Krishna Janmashtami, Hartalika Teej, Ganesh Chaturthi, Vinayaka Chaturthi, Mahalaya, Vijayadashami, Karva Chauth, Dhanteras, Diwali, Govardhan Puja, Bhai Dooj, and Devuthani Ekadashi. Vrats include all 24 Ekadashis (with Vaikuntha, Mokshada, Devuthani, Nirjala by name), Sankashti and Angarki Sankashti, plus Soma, Bhaum, and Shani Pradosh.
Can I use this calendar for past years or future planning?+
Yes. The Naksham engine covers dates from 1900 to 2100. You can look up old dates. When was Diwali in 2010? You can plan ahead too. When is the next Ekadashi in 2027? Past and future months are computed on demand and cached.
How is this different from the main Tithi Calendar page?+
The main Tithi Calendar page always shows the current month. It updates each day. This archive page shows a set month from the URL (for example, /2026/03 for March 2026). It updates each day too. Archive pages are best for bookmarks, sharing, and SEO. Each month has its own URL and metadata.
