Mayan Calendar Converter

Turn Back the Clock or Fast Forward It with the Mayan Calendar Converter

If you’ve ever been curious about how today’s date might look through the eyes of an ancient Mayan astronomer, this tool makes it simple. The Mayan Calendar Converter takes modern Gregorian dates and translates them into the Mayan Long Count, Tzolkin, and Haab calendars—or flips it the other way around. Whether you're planning a cultural project, cross-referencing historical records, or just having some time-traveling fun, this tool lays it all out for you.

What This Converter Actually Does

This calculator is built to move between two vastly different timekeeping systems: the Gregorian calendar most of us use daily, and the deeply symbolic and astronomically rooted Mayan calendar. With a single click, it shows you:

• The full Mayan Long Count date
• The Tzolkin (sacred 260-day cycle) and Haab (365-day solar year)
• Combined calendar round values
• The equivalent Gregorian date when inputting Mayan values
• Days passed since the Mayan creation date (August 11, 3114 BCE)
• Meaning behind the current Tzolkin day

And it's all wrapped into one responsive, timezone-aware interface.

Why You Might Want to Use It

This isn’t just a novelty tool. Historians, anthropologists, teachers, writers, and folks with a personal connection to Mayan heritage will find it handy. Whether you're digging into ancient texts or planning a culturally aligned event, it helps you understand time in a new light.

And if you’re simply curious about what the Long Count date was on your birthday or want to know how the Maya would mark an upcoming anniversary, this makes it happen in seconds—no charts or spreadsheets needed.

Details That Make a Difference

Live Time and Today’s Date in Both Systems

The tool continuously updates the current time and date. You can view today’s date in both Gregorian and Mayan formats without entering anything. A toggle lets you switch between 12-hour and 24-hour clocks.

Timezone Support

You can select from major timezones worldwide, from Tokyo to Guatemala. This makes it more accurate when looking at events from different parts of the world.

Automatic Input Feedback

If you change the date, time zone, or calendar direction, the tool recalculates automatically. No need to hit convert every time—just tweak a field and it does the math for you.

Visual Feedback

When a conversion runs successfully, the results area subtly animates to confirm your action. It’s a small detail, but it helps you know the tool did its job.

Answers to Questions You Might Have

What’s with the “Long Count” format?

The Long Count is a five-part number showing the total days since the Mayan creation date. It’s broken down into Baktun, Katun, Tun, Uinal, and Kin. Each unit represents a chunk of time, with Baktuns being the largest (about 394 years).

Why isn’t my input working?

If you’re entering a Mayan date, double-check that each number stays within its allowed range. The tool won’t calculate anything if those values are out of bounds. Also, for Gregorian dates, make sure you’ve picked something from the date picker.

Does this account for Daylight Saving Time?

Yes. The timezone setting takes care of all the adjustments based on your selection. You don’t have to worry about calculating the offset manually.

What’s “Days Since Creation” about?

This number tells you how many days have passed since August 11, 3114 BCE—a foundational date in the Mayan calendar. Think of it like their version of a zero point.
