  • Addressed an issue where the Framework would throw an exception is the year in the parsed date is greater or equal the year start the next era. Now, the framework will not throw such exception.
  • Updated Japanese Era dates that are formatted for the first year in an era and for which the format pattern uses “y年”. The format of the year together with the symbol “元” is supported instead of using year number 1. Also, formatting day numbers that include “元” is supported.
  • Removed dependency of single quote to output the Gannen character in Japanese Era formatting.
  • Addressed registry key setting HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Nls\Calendars\Japanese\Eras to support Japanese Era.
