How to use the Indian National Calendar Converter
- Choose whether you are converting a Gregorian date to the Indian national calendar or a Saka date to Gregorian.

- Read the Saka date, the weekday and the Vikram Samvat year.
The national calendar
The Indian national calendar has twelve months whose lengths never change. That makes it a plain solar calendar, like the Gregorian one, and each Saka date always falls on the same Gregorian date in years of the same kind.
Saka year Gregorian year − 78 (from 1 Chaitra), − 79 before it1 Chaitra 22 March; 21 March when the Gregorian year is a leap yearChaitra 30 days; 31 in a leap yearVaishakha to Bhadra 31 days eachAshvin to Phalguna 30 days eachThe page counts days from 1 Chaitra of the Saka year and adds the months before the one you picked. Going the other way, it finds which side of 1 Chaitra the Gregorian date falls on, then walks forward through the months.
Vikram Samvat
Vikram Samvat is the era most Hindu calendars in north India and Nepal use, and it runs 56 or 57 years ahead of the Gregorian year. Its months are lunisolar, so a full Vikram Samvat date needs the times of the new and full moons. This page gives only the year, and says plainly when the year depends on a new moon it does not compute.
With your numbers
- The Saka year begins on 22 March, or 21 March in a Gregorian leap year, and is 78 years behind the Gregorian year
- Chaitra has 30 days (31 in a leap year), the next five months 31, and the last six 30

Common questions about the Indian National Calendar Converter
- What is the Indian national calendar?
- It is the solar calendar the Government of India adopted on 22 March 1957, on the advice of the Calendar Reform Committee chaired by Meghnad Saha. It is printed alongside the Gregorian date in the Gazette of India, on All India Radio and on government calendars. Its years are counted in the Saka era, which is 78 years behind the Gregorian year from its New Year in March.
- How is it different from the Saka dates in a panchang?
- A panchang uses lunisolar months that follow the moon, so its months start on different days each year. The national calendar fixes every month by rule: Chaitra starts on 22 March, or 21 March in a Gregorian leap year, and each month always starts on the same Gregorian date. The month names are the same, which is the usual source of confusion.
- Why does the page give two Vikram Samvat years in March and April?
- In most of north India the Vikram Samvat year begins on Chaitra Shukla Pratipada, the day after the new moon of Chaitra, which falls in March or April and moves every year. Working out that day needs the moon's position, which this page does not compute. From May to December the year is the Gregorian year plus 57, and in January and February it is plus 56. In March and April it depends on whether the new year has passed.
- Is Vikram Samvat counted the same way everywhere?
- No. In Gujarat and parts of western India the year begins the day after Diwali, in October or November, so from the north Indian new year in March or April until Diwali the Gujarati year is one lower. Nepal's official Bikram Sambat is a solar calendar whose year begins on 1 Baisakh in mid-April. The page uses the north Indian Chaitra reckoning.
- Can I convert a date before 1957?
- Yes. The page applies the same rule backwards, so 15 August 1947 has a Saka date even though the calendar was not in use yet. Documents from before 1957 that give Saka dates used the older lunisolar or regional calendars, so they will not always match.
