В записных книжках фабрики Восход, есть клендарики, по которым можно опсчитать.
В принципе, можно посчитать вручную-главное знать, что каждый год день недели сдвигается на 1 день, а в високосные--прыгает через один.

Можно воспользоваться формулой Целлера:

Zeller's Rule

The following formula is named Zeller's Rule after a Reverend Zeller. [x] means the greatest integer that is smaller than x. You can find this number by just dropping everything after the decimal point. For example, [3.79] is 3. Here's the formula:

f = k + [(13*m-1)/5] + D + [D/4] + [C/4] - 2*C.
* k is the day of the month. Let's use January 29, 2064 as an example. For this date, k = 29.
* m is the month number. Months have to be counted specially for Zeller's Rule: March is 1, April is 2, and so on to February, which is 12. (This makes the formula simpler, because on leap years February 29 is counted as the last day of the year.) Because of this rule, January and February are always counted as the 11th and 12th months of the previous year. In our example, m = 11.
* D is the last two digits of the year. Because of the month numbering, D = 63 in our example, even though we are using a date from 2064.
* C stands for century: it's the first two digits of the year. In our case, C = 20.
