BibCal

It's the Sabbath, on the 18th day of the 10th month.

And God said, Let there be lights in the firmament of the heaven to divide the day from the night]; and let them be for signs, and for seasons, and for days, and years: And let them be for lights in the firmament of the heaven to give light upon the earth: and it was so.

This page displays the current Biblical Calendar data for any given location based on the following:

  • The day starts at sunset.
  • The month starts on the first sunset following a lunar conjunction.
  • The year starts on the first month following the vernal equinox.
  • The start of a year or a month will always be normalized based on the conditions at the Temple Mount in Jerusalem, Israel.

Based on these premises, we can mathematically calculate the date at any given location. By default, the location will be estimated based on your IP. To get the most accurate time, visit the site with your coordinates following a / in the URL.

For a multi-platform command-line app that doesn't require Internet access, get the free and open-source program bibcal. It has support for several ways of calculating historical and future dates and feast days. This website is only a simplified version of the app.

If you would like to build your own app to calculate biblical dates, take a look at the free and open source library Luminary, which is written in Clojure.
