VCR Clock Problem

[Keebler Elf]

My old VCR isn't able to recognize the current date. It won't let me enter the year 2007. Is there a way to figure out what year to use that has the days fall on the same days as in 2007?

The VCR works fine and for obvious reasons I don't want to buy another VCR.

If it is correct you best bet is 1979.

hunter is correct, 1979 will work, but so will 1990 and 2001. For those that are interested, here's a site with all kinds of nifty calendar and date calculation tools:

Hey, did anyone notice that the years that use the same calendar are consistantly 6 and 11 yrs apart? What it means I haven't a clue but I found it interesting...

(man, I need a life in the worst way lol)

6 & 11? Well, mostly.

To start with, since a year is one day longer than a simple 52 weeks (365 = 52*7 +1), calendars would rotate on a 7-year basis. But we've got these leap-years in there, which mix things up a bit.

But there are still only 14 calendars available under the current system: seven calendars with Jan 1 falling on Sun, Mon, ... Sat, in a non-leap year, and another seven with Jan 1 on Sun, Mon, ... in a leap year.

Normally, the same day of the year will fall one day earlier the next year (e.g. if your birthday is a Friday one year, it should normally be a Saturday the next year). If there's a leap year, it'll skip a day to the Sunday (366 = 52*7 +2). This leads to a six-year cycle for a bunch of years (there often being only a single leap year within a six-year (or seven-year) interval).

The apparent 11-year interval is a bit more complicated, but the underlying issues are the same. (And I'm too tired to actually go through it just right now.)

[Edited to correct the number of days in a year. Oops.]
