365 days per year divided by 7 days per week yields a year of 52 weeks and one
day. Therefore, in a normal year a day falling on a Friday this year will fall
on Thursday next year. Except in leap years, where there will be two days
difference.

So the same weekday will always be five or six years ago depending on how many
leap days there are in between.

Google 'perpetual calendar' and you'll quickly be able to see which years in the
century have the same days of the week configuration.

Today is 16 Mar, 2007 (Friday), does anyone know which historical year will
offer 16 Mar on Friday? On the other words, which historical year will offer
the same weekday on 2007 for everyday?
Thank for any suggestions
Eric
