New Britannian Calendar

The New Britannia Calendar dates restarted with “The Fall” (the lunar calamity that destroyed much of the Old World). begins 400 years after “The Fall,” also known as “Post Cataclysm” or “PC”.

The time and date in New Britannia is tied in a direct ratio to real Earth time. January 1st 2013 on Earth was January 1st of the NB year 400. Each Earth Hour is equal to one New Britannia Day. There are 28 days in each new Britannia Month (meaning each month is a little more than an Earth day). A full New Britannia Year of 336 days passes in 2 Earth weeks. A full year on Earth is about 26 New Britannia Years. This allows us to easily calculate dates in New Britannia.

The month and day names closely resemble their Earth counterparts, but are slightly different in pronunciation: Here are some important dates. Items in white are in-game events, items in orange are external events, items in red are key dates, and items in cyan are future estimated dates. All dates are based on Central time (which is where Austin is located), and may be referred to as NBT (New Britannia Time).

Trivia

 * In the Release 17 Postmortem, it was stated that New Britannian time counts from midnight on Jan 1, 2013, and each Earth hour is one New Britannia day.
 * The calendar was first implemented in Release 18.
 * New Britannia shares the same 28-day month, 336-day year calendar as the Ultima series.
 * On the date of the Cataclysm (September 2, 1997) there was a solar eclipse. This was a total eclipse in the UK, but only a partial eclipse in the USA.
 * September 1997 was also the end of the beta for (and subsequent launch of) Ultima Online. The beta ended with a bang, as players were treated to an "end of the world" scenario with Shadowlords, demons, and other evil creatures slaughtering every character in sight.
