Calendar dating back to 1980 dating a guy 2 years younger
In 1582, Pope Gregory XIII determined that the Julian calendar was incorrect: each day was just a little bit too long and the human calendar wasn't keeping up with nature's calendar.To solve the problem, Pope Gregory XIII created what is known as the Gregorian calendar.In the United States, we normally write dates with the month first, the day second, and the year last.For example, we write October 15, 1970 as 10/15/70.For suggestions, concerns or complaints regarding a specific web site within the USGen Web Project, please use the Contact Form.
The 8870 formula using the above date and age as an example: Date of death - 1889 May 6 = 18890506 (where 1889=year, 05=month, 06=day)Age at death - 71 yrs 7 mo 9 days = 710709 (where 71=years, 07=months, 09=days)Subtract 710709 from 18890506 =18179797Subtract the Constant (8870) from 18179797Result = 18170927 (where 1817 = year, 09 = month, 27 = day.
Before that date, the government observed March 25 as the first of the year, but most of the population observed January 1 as the first of the year.
For this reason, many people wrote dates falling between January 1 and March 25 with both years, as in the following examples.
This new calendar changed the first day of the year to January 1 and also jumped ahead by 10 days to make up for the lost time.
The practice of double dating resulted from the switch from the Julian to the Gregorian calendar.
