Indian Saka Calendar Converter — National Calendar & Gregorian
Convert any Gregorian date to the Indian National Calendar — the Saka calendar — and back. The Saka calendar is the official civil calendar of India, used alongside the Gregorian calendar on government documents and communications. Furthermore, the year starts on 22 March (21 March in leap years) and the result shows the Saka day, month name, year in SE (Saka Era) and whether the year is a leap year affecting Chaitra's length.

The twelve months of the Indian Saka calendar
The Saka calendar has twelve months. Furthermore, the first six months each have 31 days and the remaining six months have 30 days each — except Chaitra in leap years, which has 31 days. The year starts at the vernal equinox in March.
| Month | Name | Days | Gregorian start (approx) |
|---|---|---|---|
| 1 | Chaitra | 30 (31 in leap) | 22 March |
| 2 | Vaisakha | 31 | 21 April |
| 3 | Jyaistha | 31 | 22 May |
| 4 | Asadha | 31 | 22 June |
| 5 | Sravana | 31 | 23 July |
| 6 | Bhadra | 31 | 23 August |
| 7 | Asvina | 30 | 23 September |
| 8 | Kartika | 30 | 23 October |
| 9 | Agrahayana | 30 | 22 November |
| 10 | Pausa | 30 | 22 December |

| 12 | Phalguna | 30 (29 in leap) | 20 February |
How the Saka calendar works
The Saka Era begins in 78 CE — the year of the Saka dynasty's rise to prominence in India. Furthermore, the Saka year equals the Gregorian year minus 78 for dates from 22 March onwards, and minus 79 for dates from 1 January to 21 March.
Months 1–6 = 31 days each (Chaitra through Bhadra)
Months 7–12 = 30 days each (Asvina through Phalguna)
Chaitra in leap year = 31 days (aligned with extra Gregorian day in February)
Why the Saka calendar aligns with the Gregorian year
The Saka calendar is a solar calendar like the Gregorian calendar — both track the solar year of approximately 365.25 days. Furthermore, the months are fixed relative to the seasons, unlike the Islamic or Hebrew calendars. This means converting between Saka and Gregorian involves only a year offset and a fixed month start day — making it one of the simpler calendar conversions.

What is the Indian Saka calendar?
The Indian National Calendar (Saka Era) is India's official civil calendar alongside the Gregorian. Furthermore, the Government adopted it in 1957 after the Calendar Reform Committee's work. The calendar standardised India's diverse regional calendars into one national system.
The Saka Era dates from 78 CE — traditionally King Kanishka's coronation year. Furthermore, the year starts at the vernal equinox in March. The calendar uses the same solar year length as the Gregorian and aligns months with the seasons.
Where the Saka calendar appears in India
India's Gazette Extraordinary publishes all official notifications with both Gregorian and Saka dates. Furthermore, Indian national holidays carry Saka dates in government communications. Moreover, All India Radio announces the Saka date daily alongside the Gregorian date.
Saka calendar versus Hindu religious calendars
The Saka calendar is India's standardised national civil calendar. Furthermore, it differs from the Hindu Vikram Samvat used for religious purposes. Moreover, the Saka calendar has fixed month lengths — unlike lunisolar Hindu calendars that vary based on the lunar cycle.
Why the Saka calendar matters
India is a major global economic partner. Furthermore, official Indian government documents — gazette notifications, legal orders, parliamentary records — carry Saka dates alongside Gregorian dates. Understanding Saka dates helps international organisations accurately cross-reference Indian government publications and legal instruments. Moreover, the Saka calendar appears on Indian stamps, coins and government stationery.
Historical research on post-independence India requires Saka calendar awareness. Government records from 1957 onwards often appear in Saka format in official publications. Furthermore, academic researchers working with Indian government archives, legislative records and policy documents encounter Saka dates regularly. Moreover, journalists and analysts following Indian government communications benefit from quick Saka-to-Gregorian conversion.
How the Saka calendar supports Indian national identity
Adopting a unified national calendar was part of India's post-independence effort to create common national institutions. Furthermore, the Saka calendar draws on ancient Indian heritage — the Saka Era name has appeared in Indian inscriptions since the 1st century CE. Moreover, using the Saka calendar in official communications honours this heritage while providing a standardised system that works alongside international Gregorian dating.
