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.



Input

The input is a sequence of datasets. The end of the input is indicated by a line containing one zero. Each dataset consists of two integers m and d separated by a single space in a line. These integers respectively represent the month and the day.

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.

Tuesday
Wednesday
Thursday
