ELI5: Why do we divide the days of the year into 7 months of 31 days, 4 months of 30 days and 1 month of 28/9 days?

Wouldn't it make more sense to take a day off two of the months of 31 and add them to February so that it has 30 days in it? Then we would have 5 months of 31 days and 7 of 30 days. And on leap years we would have 6 months with 30 days and 6 months of 31 days. 28 days in February just seems weird.

There's an argument about actually having 13 months all with 28 days. Which would be 364 days. The last day of the year would be a single day under no month. Then when there is leap year there will be a additional single day at the end of the year that is not part of any month either. What this would do is it would make every day for every month fall on the same numbered day. (i.e. The 1st would always be a Sunday and and the 4th would always be a Wednesday)
