Why are there 30 days in some months and 31 days in others?

    Originally, we followed what was called the Julian Calendar (which stated that there were 365 1/4 days in a year), but it was found to be slightly inaccurate by Pope Gregory XIII. Due to the Julian calendar, dates became increasingly confused. Thus, Gregory set about making what we now call the Gregorian calendar. However, he kept the same dates and days that were in certain months, changing February to have an extra day once every four years; essentially, this causes the actual time it takes to revolve around the sun to be equal to the days we put in the year. Otherwise, each month would have 30.4 days, which would be really confusing on that .4 day, to try and figure which month it was.
