Key:
Weeks total of school (X):
This is simply the week number from when you start...to when you end. (41 at my school)
----
Week currently going (Y):
The week number that you are currently on. (As of April 8th, the week number is 34)
----
Day numbers (Z):
Monday = 0
Tuesday = 1
Wednesday = 2
Thrusday = 3

--------------------------------------
Some information:
Current Date: April 8th, 2008
End Of School: May 23
Current Week of school: 34
Total Weeks: 41
Day: Tuesday (1)
--------------------------------------
Structure of the equation:
((7-2)X) - ((7-2)Y) - Z
Or
((5)X) - ((5)Y) - Z
--------------------------------------
Let’s use todays information and plug it into the equation:
((7-2)41) - ((7-2)34) - 1
Or
((5)41) - ((5)34) -1
We get: 34. Count on a calender to may 23rd and it should be 34 days.
Remember: This works for all weeks, but does not exclude weeks we are off of school. Always be sure to get the day numbers right. Monday MUST equal 0 and Friday MUST equal 4.
