Guide

Convert Myanmar calendar dates and Gregorian dates

This Burmese Date Converter changes Gregorian dates into modern Myanmar calendar dates and converts explicit Burmese calendar input back into Gregorian dates. It is useful for checking Myanmar year, month, and day values against a Gregorian record.

The converter uses a Julian-day Myanmar calendar algorithm with era constants and watat year handling. Reverse input uses YEAR-MONTH-DAY, and Second Waso is marked with -L when needed.

The page is a calendar conversion tool, not a holiday calculator or historical almanac. It validates month, day, and Second Waso combinations before returning a Gregorian date.

What it handles

Modern Myanmar calendar conversion coverage

The converter supports Gregorian to Burmese and Burmese to Gregorian conversion. Results include the Myanmar year, month label, day, year type, weekday, and whether the date is Second Waso.

Second Waso is explicit because it only appears in watat years. The reverse converter checks that the -L marker is possible for the entered year and month.

Gregorian to Burmese

Enter a Gregorian date and return the corresponding modern Myanmar calendar date.

Burmese to Gregorian

Enter YEAR-MONTH-DAY, with -L only for Second Waso, and convert the date back to Gregorian.

Watat-year validation

Invalid Second Waso, month, or day combinations are rejected instead of being normalized.

How to use

Use the Burmese conversion modes

Choose Gregorian to Burmese when you have a standard Gregorian date. Choose Burmese to Gregorian when the source date is already written as a Myanmar calendar date.

For reverse input, use numeric YEAR-MONTH-DAY. Month 04 is Waso; add -L only when the date is specifically Second Waso in a watat year.

Choose Gregorian to Burmese

Use this direction for Gregorian 2026-06-30. The verified output is Burmese 1388-04-16.

Choose Burmese to Gregorian

Use this direction for input such as 1388-04-16. Add -L only for Second Waso dates.

Do not mark regular Waso as Second Waso

The -L suffix changes the meaning of the date. If the date is not Second Waso, leave the suffix off.

Examples

Reference conversions from the local implementation

These examples are produced by the same conversion functions used by the form. They show the accepted reverse-input syntax and the Gregorian date returned by the round trip.

Gregorian date to Burmese date

2026-06-30 -> 1388-04-16

The Gregorian date 2026-06-30 converts to Burmese 1388-04-16, Waso 16.

Burmese date to Gregorian date

1388-04-16 -> 2026-06-30

The Burmese input 1388-04-16 converts back to Gregorian 2026-06-30.

FAQ

Burmese date conversion notes

Myanmar calendar conversion has special leap-year behavior, especially around Waso. These answers explain the input markers and the limits of the page.

What does -L mean?

-L marks Second Waso. Use it only with month 04 when the Myanmar year actually has Second Waso.

Does this calculate Myanmar holidays?

No. The converter returns calendar dates and does not calculate holidays, festivals, or observance rules.

Why can invalid dates be rejected?

Reverse conversion validates the Myanmar fields after conversion so impossible month, day, or Second Waso combinations do not silently shift.

Reference

Calendar implementation reference

The implementation uses a published Julian-day Myanmar calendar algorithm with modern era constants and watat-year logic. The page labels that basis so users do not mistake it for a manually curated almanac.
