If they made me God Emperor for a day the first thing I would do would be to change the calendar we use. Having every month be a different number of days, causing the day of the weeks to shift from month to month is crazy. Either we should do 12 months of 30 days, with a 5/6 day "extra" week at the end of the year, or 13 months of 28 days with New Year's/Leap Day as an intra-monthly day. I'm in favor of the latter, that way every single month would be exactly four weeks and be identical. No more buying calendars every year, it would always be the same.
