Atlantean Date and Time:


The Atlantean Date Converter is a fun tool for converting Earth dates to Atlantean dates in the fictional, imaginary timeline from the exciting, multi-genre, bestselling series The Atlantis Grail by Vera Nazarian.

For example, want to find out your Atlantean Birthday? Simply enter your full Earth date (month, day, and year required for accurate conversion) and time (optional) in the form above and the Atlantean result is displayed automatically.

NOTE: The converter doesn't go further back than April 12, 10,502 BCE because that date translates to Day Zero on the Atlantean Calendar and there are no earlier dates before that.

To enter dates BC/BCE, use a negative number for the year. For example, to enter the year 345 BCE enter "-345" in the form.
