If today is Friday, April 16, 2004, what day will it be in 100 days

If today is Friday, April 16, 2004, what day will it be in 100 days


There are seven days in a week. Now let's assume that Friday is the beginning of a week. There are two days in 100 days: 100 divided by 7 = 14 (weeks). From Friday, plus two days, it is Sunday. Therefore, Friday, April 16, 2004, and another 100 days is Sunday



If today is Friday, April 23, 2004, what day is it in 100 days? What's the trick?


Every week will return to Friday, and 100 days is 14 weeks (98 days) and 2 days, so after 14 weeks, it will still be Friday, and two more days will be Sunday



The opening of the Olympic Games on August 8, 2008 is Friday. What day is August 8, 2009?
What I want is how to calculate. You can give me an example


Saturday
First of all, calculate whether 2009 is a normal year or a wet year - 2009 △ 4 = 502 + 1, except for not enough, so it is a normal year. There are 365 days in a normal year, then use 365 △ 7 (7 days a week) = 52 weeks + 1 day, and finally use Friday plus 1 day to be a Saturday



The Olympic Games will open on August 8, 2008. It's Friday and close on August 24. What day is it?


24-8 = 16 / 7 = 2.2 Friday + 2 = Sunday
