Happy Monday!

Harry and Larry are twins,
born to the same parents in 1987.

Harry is the elder twin, born
twenty minutes before Larry,
but Harry celebrated his 21st birthday
two days before Larry did.

How is this possible?

HERE is the solution.

ANSWER: John was born at 11:50 PM on February 28, 1987 while, James was born twenty minutes later at 12:10 AM on March 1, 1987. The year they celebrated their 21st birthday was 2008 - a leap year - adding an extra day between the twins' birthdates.
