Gregorian Calendar Sheets of the Years 1582 - 2399

This book contains Gregorian calendar sheets with day of week, day of month and month for the years 1582 to 2399. The Gregorian calendar replaced the Julian calendar of Julius Caesar on 15 October 1582 and since then it has established itself worldwide. The Gregorian calendar is cyclical and repeats itself every 400 years. Assuming the current leap year rule remains unchanged, the calendar pages can of course be used for the years after 2399. An easy formula is given for calculating mentally the page corresponding to particular years.
