The Fixed Calendar

User Friendly

Easy To Memorize

The Fixed Calendar can be used every year without change. I’ve been using it for more than a decade in-house for my micro business. I have been improving it over time and today I present it in a layout more familiar to users of the Gregorian Calendar. The reasons for adopting the Fixed Calendar and abandoning the Gregorian Calendar are described in full HERE.

As you can see, there are 13 months and 364 week days. The Fixed Calendar is a solar calendar, which follows the Earth’s revolutions around the Sun. Lunar calendars follow moon cycles and there are approximately 13 per year, but because they are not exact, they gradually drift across solar calendars.

Here is the Fixed Calendar with the Gregorian Calendar included for convenient conversion. It takes a little getting used to.

Start using the Fixed Calendar in private, for your personal schedule – things that don’t affect others, such as your exercise routine. If you have a small business, use it in-house for more accurate account-keeping. The following version of the calendar and conversion table shows quarterly periods, all of which have exactly 91 days, unlike the Gregorian Calendar:

The International Fixed Calendar was created by Moses Cotswold in 1902. It looked like this:

In July, 2016, I published a conversion table for Gregorian Calendar based on Moses Cotsworth’s layout. Over a 7 year period of continual use and modification, it eventually looked like this:

I hope you find the new layout at the top of this post more user friendly. You can read more about the Fixed Calendar HERE. I hope you find my research and experimentation interesting. Feel free to comment below.
