* It has an easy-to-remember 11 straight months of 30 days each, ending the confusion of variable month lengths.
* It offers three identical business quarters of 90 days each.
* It still only has one "leap day," and puts it in December, at the very end of the year.
* It allows easy calculation of ordinal days (number of days in the year), since almost almost all months are equal in length and each month starts again after 30 days.
* Months progress in a more logical fashion, with each month within a year's calendar year starting two weekdays later than the previous month did (if January starts on a Monday, February starts on a Wednesday.)
* Its logical design makes calculating any weekday an easy task (If January starts on a Monday, March 1 will be a Friday, Mar. 8 is a Wednesday, so Mar. 9 is a Thursday.)
