SNAP Calendars Questions

Every non-leap year have 365 days. i.e (7x52+1) days.

Leap year have 366 days i.e ( 7x52+2) days

A cycle of four years will have 1+1+1+2 days i.e 5 days shift  

For the days to repeat, the shift should be a multiple of 7.

A cycle of four years if repeated 7 times will have a 35 days shift. Every day will repeat after 4x7 (28 years).

After 1996 the cycle will be in 1996+28 = 2024 

There can be 28(February in a Non-Leap year), 29 (February in a Leap year), 30 and 31 days in a month.

For 28 days, if a month ends in a Wednesday, there are 4 days each of Monday, Tuesday, Wednesday, Thursday, Friday, Saturday and Sunday.

For 31 days, if a month ends in a Wednesday, we have 5 days each of Monday, Tuesday and Wednesday after distributing 28 days equally to the 7 days.

Therefore, if the month is not specified, we can have both 4 and 5 Mondays in a month. hence, option D.
