I want to find the day for every date?

Question

know how?

Answer 1

There is a formula called Zeller's Congruence. I have supplied some links below on how to calculate it.
The second link is an applet

Answer 2

When you find a perpetual calendar, it may not show all dates for all time. If you remember that the calendar repeats exactly every 400 years, you can figure out the day.

Today is Monday, August 6, 2007. August 6, 2407 is also a Monday.

That works because the calendar gains one day each year, except it gains two days on leap year *(every 4 years), except it doesn't have a leap year in years divided by 100, except there is a leap year in years divided by 400. So there are 97 leap years in 400 years and the calendar gains 497 days. 497 days / 7 days in a weeks = 71 weeks. The calendar gains exactly 71 weeks every 400 years, which is how I know that August 6, 200000000000000000000000007 will be a Monday.

Answer 3

If you have a copy of Excel, you have a built-in perpetual calendar (at least for dates after Jan. 1 1900). Check out the Help on the Weekday function.

Answer 4

Try an Internet search for the phrase "perpetual calendar". This will give you some algorithms that can produce the day of the week for any given date in history.
