GREGCAL - Gregorian calendar |
| Wersja polska | English version |
Given a date, your task is to print the weekday.
Notice: In Julian calendar leap years were years which were divisible by 4. According to Gregorian calendar, leap years are years which are divisible by 4 excluding these which are divisible by 100 and are not divisible by 400.
Input
The first line of the standard input contains one integer t (t<101) which is the number of test cases.
In each of the next t lines there is a date in format yyyy:mm:dd (1582<year<2010).
Output
For each test case print weekday (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday or Sunday) for given date or ERROR if the date is incorrect.
Example
Input:
2
1959:10:10
1962:02:29
Output:
Saturday
ERROR

@Jander: Why? There are many reasons: You're the best Perl shortener, you've got most of shortest solutions, you've beaten Zoltan and shinh,... |

@HWK: Why, thank you. Maybe I just need to get out more often, rather than devoting my time to these tasks :-) |

Piotr, could you please check why solution #5022761 fails? I checked every date from 1970 to now comparing it to UNIX' "date" tool, it works flawlessly. |

1600:02:29 - why You print for this test ERROR? 1600 is a leap year. |

At home solution 3879906 gives correct results for Python 2.4 and 2.6. Why not for 2.5? Isn't the locale-setting not english? |
