Union Standard Year

As part of the Time Keeping Reform of 5050, the Union adopted a new standard year comprised of ten months each divided into five weeks of ten days, for a total of 500 Union Standard Days.

With the reform, new calendar was adopted with 01/01/2220 OTT (the previous de facto standard) also being the first day of the new calendar being OneDay-Red Week -First Month 1 UST. The changes officially took effect on 01/01/5051 OTT or OneDay-Red Week -First Month 2069 (as part of the transition, 12/31/5050 OTT was skipped.)
