Description

By default, the calendar is set according to the locale of the operating system, and users can show an additional calendar. For zh-CN and zh-SG locales, an additional calendar shows the lunar month and date and holiday names in Simplified Chinese (Lunar) by default. For zh-TW, zh-HK, and zh-MO locales, an additional calendar shows the lunar month and date and holiday names in Traditional Chinese (Lunar) by default. If you enable this policy setting, users can show an additional calendar in either Simplified Chinese (Lunar) or Traditional Chinese (Lunar), regardless of the locale. If you disable this policy setting, users cannot show an additional calendar, regardless of the locale. If you do not configure this policy setting, the calendar will be set according to the default logic.
