Want to figure out the date that is exactly two hundred fifty five days before Aug 21, 2068 without counting?
Your starting date is August 21, 2068 so that means that 255 days earlier would be December 10, 2067.
You can check this by using the date difference calculator to measure the number of days before Dec 10, 2067 to Aug 21, 2068.
December 10, 2067 is a Saturday. It is the 344th day of the year, and in the 49th week of the year (assuming each week starts on a Sunday), or the 4th quarter of the year.

The short form for this date used in the United States is 12/10/2067, and almost everywhere else in the world it's 10/12/2067.
In some cases, you might want to skip weekends and count only the weekdays. This could be useful if you know you have a deadline based on a certain number of business days.
