Question

•How did the person who invented the calendar know what day it was?

•Why did we decide to give February just 28 days when lots of other months have 31 days? Couldn’t we have just taken some of the 31st days from other months and added them to February?​

Answer 1

Answer:

• But Aloysus Lilius, the Italian scientist who developed the system Pope Gregory would unveil in 1582, realized that the addition of so many days made the calendar slightly too long. He devised a variation that adds leap days in years divisible by four, unless the year is also divisible by 100

• This is because of simple mathematical fact: the sum of any even amount (12 months) of odd numbers will always equal an even number—and he wanted the total to be odd. So Numa chose February, a month that would be host to Roman rituals honoring the dead, as the unlucky month to consist of 28 days.
