What day is today?

Your task is to write a program which reads a date (from 2004/1/1 to 2004/12/31) and prints the day of the date. Jan. 1, 2004, is Thursday. Note that 2004 is a leap year and we have Feb. 29.

The number of datasets is less than or equal to 50.

Output

For each dataset, print the day (please see the following words) in a line.
