When was Feb. 1? Most would say, "Today, Wednesday." Those who support some calendar reforms say "yesterday, Tuesday," or "this past Sunday."
For proponents of the 30x11 Calendar and the Common-Civil-Calendar, January should have ended on the 30th day of the month, making the 31st their "Feb. 1."
For supporters of the Symmetry454 Calendar, New Earth Calendar, and the 13-month Sol Calendar (and other 13-month, 28-day month proposals,) Sunday, Jan. 29, was the day for welcoming February (though the Symmetry454 and New Earth calendars would have called it a "Monday," since all weeks in these calendars start on Mondays.)
This first Date of Divergence in these calendars represent a call for societal change - a change in how we view the year.
The one message they all convey comes across loud and clear: the Gregorian months - which start 2006 numbered in this fashion: 31, 28, 31, 30 - cry out for symmetry, order and a logical progression of days.
It's not too hard to envision a different, better, way to number our months, thanks to many visionary reformers who have proposed calendar change on a global scale. We should listen to what they have to say.
