May 1st, 2009 is Friday. Can you work out what day is July 1st, 2010?

2009 and 2010 are both ordinary years. In the second year of the ordinary year, the number of weeks plus one, that is, May 1, 2010 is a Saturday. There are 92 days from May 1 to July 1, 2010. 92 / 7 = 13.1, that is, 13 Saturdays have passed, and July 1, 2010 is a Sunday

April 21, 2008 is Monday. What day is April 21, 2009?

February 2009 had only 28 days,
So it's 365 days
365 / 7 = 52 + 1
So it's Tuesday

January 1, 2008 is Tuesday, January 1, 2009 is Sunday ()
A. Three B. four C. five D. six

366-1 + 1 = 366 (days), 366 △ 7 = 52 (weeks) Because January 1, 2008 is Tuesday, 2 + 2 = 4, so January 1, 2009 is Thursday

If September 10, 2007 is Monday, what day is August 8, 2008?

Calculate the days from September 10, 2007 to August 8, 2008 = 333 days
333 / 7 = 47 + 4 days
The 10th is Monday, and the 8th is 1 + 4 = 5
So the 8th is Friday

The national day of 2004 is Friday. Do you know what day it is on December 1st, 2004? This is a Mathematical Olympiad problem

October + November = 61 days
61/7=8… five
5+5-7=3
Wednesday

National Day in 2004 is Friday. What day is December 1st, 2004?
