LOGIC EXPLATION:-

  • Every YEAR ,day on date increase by +1 but sometime increase by +2 due to Leap Year.

LEAP YEAR:-

A leap year is the year in which there are 366 days . One day increase  in february.

  • Day on B'Day before 29th february  has +2 next year of leap but day on date after 29th feb has +2 on the same year.

For Example:-

In 1996(leap year)

A=11 january (Thursday)

H=5 September(Thursday)

But In 1997

A=Thur+2 =Saturday

H=Thur+1=Friday
