Day of the week

Given a date, can you compute its corresponding day of the week? For instance, the day of the week of the date 2 October 2024 is Wednesday.

Remember that the days of the week are Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday. Also, common years have 365 days. At most once every four years, we have a leap year of 366 days. 2024 is a leap year.

These are the months and their lenghts:

January: 31 days
February: 28 days in common years and 29 days in leap years
March: 31 days
April: 30 days
May: 31 days
June: 30 days
July: 31 days
August: 31 days
September: 30 days
October: 31 days
November: 30 days
December: 31 days
