Re: Re: Saturdays and Sundays

Here is an another approach.. if you glance at a calendar, youll notice that the only times there are 5 sats in a month, is when the 1st of 30 day month falls on a fri or sat.. or in a 31 day month, a thur, fri, or say.. So, you could simply test the weekday the first of the month has, and the number of days in the month.. and the num of sats in the month is either 4... or 5. :) Jason On 9/1/05, Brian P.
