By foul moon
Because I know that I will need it...

def IsFullMoon(dateToCheck as date):
two_digit_year as decimal = dateToCheck.Year - ((dateToCheck.Year/100)*100)
remainder as decimal = two_digit_year %19
if remainder > 9:
remainder -= 19;
phase as decimal = (remainder * 11) %30
if dateToCheck.Month == 1:
phase+=3
elif dateToCheck.Month == 2:
phase+=4
else:
phase+= dateToCheck.Month
phase+=dateToCheck.Day
if dateToCheck.Year < 2000:
phase -= 4
else:
phase -= 8.3
phase = phase % 30
return 14.5 < phase and phase < 15.5
Expected usage:
if IsFullMoon(DateTime.Now):
raise SqlException("""Transaction (Process ID 179) was deadlocked on lock resources with another
process and has been chosen as the deadlock victim. Rerun the transaction.""")
Update: I am still struggling with the code for WasChickenSacrifised(), will be glad to get suggestions...

The implementation is simple if you ask a vegetarian to write it:
public class ArcaneArts {
public bool WasChickenSacrificed() {
}
}
:^P
Where are the unit tests? Will you mock then Moon object?
:-)
return Moon.Capacity == Moon.Length
seriously, you can use Hebrew Calendar and check for day==15
def IsWitch:
@Ken,
Using the Hebrew calendar would be too easy... :-)
Regardless, is it guaranteed that 15th of a month is full moon?
The Hebrew Calendar is based on the moon. ie, in the firsdt day the moon is "empty", at the middle it's "full", and towards the end of the month the moon is emptying again.
That's how it's defined.
In old times, they did not even had a calendar. they just looked at the skies and when the moon was empty, it was decided as a new month.
