Symmetry454

The Symmetry454 calendar (Sym454) is a proposal for calendar reform created in early 2004 by Dr. Irv Bromberg, an assistant professor at the University of Toronto, Canada (retired in 2018). It is a perennial solar calendar that conserves the traditional month pattern and 7-day week, has symmetrical equal quarters, and starts every month on Monday.
