About Japanese Calendar: Wareki
Japanese Calendar opens on today — the Japanese era date, the Rokuyo and the season are already there.
WESTERN YEAR TO JAPANESE ERA
• 令和 (Reiwa), 平成 (Heisei), 昭和 (Showa), 大正 (Taisho), 明治 (Meiji)
• Correct era boundary dates, including the 元年 (first year) convention
• Convert in both directions
WHAT THE DAY CARRIES
• 六曜 (Rokuyo) — 大安 (Taian, most auspicious) through 仏滅 (Butsumetsu), used when picking wedding and ceremony dates
• 二十四節気 (24 solar terms) such as 立春 (Risshun, start of spring)
• Japanese public holidays, including substitute holidays
• 干支 (zodiac) for the year
COMPUTED, NOT COPIED
Rokuyo comes from the traditional lunisolar calendar, and solar terms from the sun's actual position — both calculated on your device. Holidays follow the statutory rules rather than a hand-typed list.
Every Japanese term is shown in its original form with an English explanation.
