A tool to switch between the Gregorian and Japanese calendars for the date displayed on the Windows 11 taskbar

You can switch the date display on the Windows 11 taskbar between the Gregorian calendar and the Japanese calendar in "Settings (Regional Settings)."

However, to switch between the Gregorian and Japanese calendar displays,Start buttonRight-click > Settings > Time and Language > Language and Region > Regional Settings > Change Format, then select from the right side of Calendar.

In other words, if you open "Settings" from the right-click menu of the Start button and switch between Gregorian and Japanese calendar display, you will need to click eight times to make the change.

So I created a tool that allows you to easily switch between Gregorian and Japanese calendar display with one or two clicks (double click).

The only supported OS is Windows 11 (Japanese).

"SeirekiWarekiSwitching" is a tool to switch between the Gregorian and Japanese calendars for date display.
