Answer 18

Okay so we know...February 27th, 2017 is a Monday. It is the 58th day of the year, and in the 9th week of the year (assuming each week starts on a Sunday), or the 1st quarter of the year. There are 28 days in this month. 2017 is not a leap year, so there are 365 days in this year. The short form for this date used in the United States is 2/27/2017, and almost everywhere else in the world it's 27/2/2017...

Answer 19

@ParthKohli and @dan815 are RIGHT! :D

Answer 20

friday
2020

Answer 21

no they both are wrong actually.
Monday +4days NOT 5days.
Since this year it's on 2016 monday
and another leap year happens in 2020 WHICH IS 4 YEARS.
The days would be Monday +4days NOT Monday +5days....just saying....

Answer 22

No wait.....You don't count monday -_- so it is a Saturday -_-

Answer 23

Is it easy to find the next leap year which matches all the days with 2016 ?

Answer 24

seven leap years...

Answer 25

that simple ?

Answer 26

each leap year adds 5 (mod 7)
so you'll have to have it seven times to get back to the same day

Answer 27

are you also accounting for that 400 years thingy ?

Answer 28

nope.

Answer 29

thankfully, the next such leap year will only be in 35 years so that 100 years and 400 years thing will not kick in

Answer 30

Years 2016 and 2016 + 7*4 will have the same day names for all calendar dates ?

Answer 31

if a leap year is skipped, then the next leap day will be
7*365 + 366 (mod 7)
== 2 (mod 7)

Answer 32

for 2016 and 2016 + 7*4 yes, that should be true

Answer 33

Awesome!
