Hello everyone, I have no ideas on how to resolve this problem !
Valentine's Day ( February 14th ) fell on a tuesday in 2006. On what day of the week will Valentine 's day fall in 2020 ???
Does someone can explain me how to answer this ?
Thank you,
Best, Thalys !
The day advances one day for each non-leap year and two days for each leap year
There are 14 Valentine's Days that occur between 2006 and 2020
There are 3 leap years in this period 2008, 2012 and 2016, and 11 non-leap years
So the number of days that advance = 3(2) + 11(1) = 17 days
So....Valentine's Day will fall on Friday in 2020
