Calendar Wiki Welcome to the Calendar Wiki! This is a site all about calendars - historical ones, new ones, and discussions about them: for the scientist, astronomer and the calendar enthusiast. To write a new Calendar Wiki article, enter the page title in the box below. Featured article The Symmetry454 Calendar (Sym454) is a proposal for Gregorian calendar reform developed by Dr. Irv Bromberg of the University of Toronto, Canada. It is a perpetual solar calendar that conserves the traditional 7-day week, has symmetrical equal quarters, and starts every month on Monday. All months have a whole number of weeks, so no month ever has a partial week. Each day number within a month falls on the same weekday in all months. All holidays, birthdays, anniversaries, etc. are permanently fixed. All ordinal day and week numbers within the year are also permanently fixed.
