Background The Japanese calendar has era names that change with the reign of the Japanese emperor. Since most of the modern age of computing has occurred in the Heisei era, much of the software has support limited to that era. A new era name was expected with the 2019 Japanese imperial transition. However, since the change of eras is infrequent, most software has not been tested to ensure that it will behave correctly with an additional era.

In early April 2019, the new era name was announced to be Reiwa for "beautiful harmony." Documented errors Some minor problems have been reported due to improper handling of the era transition.
