Proposed New Standard Year:
13 equal sized months: 28 days x 13 months = 364
The remaining day is New Year's Day which belongs to no month and on leap year the extra day gets combined with New Year's Day.
Here's the tweet where I originally saw this idea: http://kcd.im/13-cal
The reason this is helpful: If someone says, "I'll see you on the 19th," you know it's on a Thursday. It doesn't matter what month, it doesn't even matter what year, it's going to be on a Thursday.
For a more complete history, I found this Wikipedia article: https://en.wikipedia.org/wiki/International_Fixed_Calendar
Looks like this has been tried before. Maybe we can make it happen now, 100 years later.
