Are there 52 Fridays in a year?

Hi,

I answered a simple DS question wrong and it's because of my analysis that there must be 52 Fridays in a Year (although I wish there were most Fridays than any other day in the year, it's story for another time). This is how I got to it..

365 divided by 7 is 52 with 1 day left. If Jan 1st starts on a Monday, then Dec 31st ends on a Tuesday. If it were a leap year, then Dec 31st ends on a Wednesday. Ahh damn! I answered my own question, if Jan 1st starts on a Thursday then there are 53 Fridays. I will continue with the posting though; some one else may find it useful and avoid the pitfall.

Thanks for reading this,
Calista.

There may or may not be an extra Friday apart from the guaranteed 52 in a given year, be it an ordinary or a leap one.
