Why it Matters

Indian festivals, anniversaries, and official records often use the Vikram Samvat or Shaka Samvat era rather than the Gregorian year. A quick converter bridges the two so you can read a samvat year at a glance or work out which Gregorian year a traditional date falls in. It's a handy reference for anyone juggling both systems.

What this tool does

The Hindu Calendar Converter translates dates between the Gregorian calendar and two widely used Indian eras — Vikram Samvat (VS) and Shaka Samvat (SS) — in either direction, and shows the approximate lunar month for context.

How it works

It applies the standard era offsets around the ~22 March Chaitra new year (VS ≈ Gregorian + 57, SS ≈ Gregorian − 78) and maps the date to its approximate lunar month. The logic is a pure function and runs fully offline.

Approximate — for reference

The era years are accurate, but the Hindu calendar is lunisolar. The exact lunar month, tithi, and paksha drift year to year and require a full panchang to compute. Treat the lunar month shown as a guide, not a precise reading.

Frequently Asked Questions

How do you convert a Gregorian year to Vikram Samvat?

Vikram Samvat is roughly the Gregorian year plus 57 once the era new year (around 22 March, Chaitra Shukla Pratipada) has passed, and plus 56 before it. So a date in May 2025 is Vikram Samvat 2082, while early January 2025 is still 2081.

What about Shaka Samvat?

Shaka Samvat is approximately the Gregorian year minus 78 after the Chaitra new year, and minus 79 before it. May 2025 corresponds to Shaka Samvat 1947. The Shaka era is the basis of India's official National Calendar.

Why is the conversion described as approximate?

The era years are accurate, but the Hindu calendar is lunisolar: the exact lunar month, tithi (lunar day), and paksha (fortnight) shift relative to Gregorian dates each year and need a full panchang to compute. This tool gives the era year precisely and the lunar month as a guide.

Why can one era year cover two Gregorian years?

Because the era year begins around 22 March, not 1 January, a single Vikram or Shaka Samvat year spans parts of two Gregorian years. When you convert from an era year, the tool shows the primary Gregorian year and the two-year span.

Is my date stored anywhere?

No. The conversion runs entirely in your browser. Nothing you enter is uploaded, logged, or stored — refreshing the page clears everything.
