wareki converts between Japanese calendar and western calendar.

Description

wareki converts between Japanese calendar and western calendar.

When converting from the Western calendar to the Japanese calendar, the era of the Japanese calendar is automatically determined according to the Western calendar. The year of Western calendar can be omitted and the default value is the system date.

By default, the Japanese era is output with one uppercase letter (e.g. R) but can also be output with kanji (e.g. 令和) You can also convert from Japanese calendar to Western calendar by specifying an option.

wareki support Reiwa, Heisei, Taisho, Meiji.
