When was the enrollment/graduation year?

"If born in Showa 63, is this year a bad luck year (Yakudoshi)?" Calculating in your head is a source of mistakes. In such cases, use the Age Chart that you can understand at a glance.
What you can understand with the Age Chart
With this tool, you can check the current "Western Calendar", "Japanese Calendar", "Age", and "Zodiac" in a list.
1. For Resume Creation
Ideal for checking enrollment and graduation years for junior high school, high school, and university. If you use the automatic calculation function, just by entering the date of birth, you can list the years of major life events such as "elementary school enrollment" and "university graduation". You can also prevent calculation errors for early birthdays (born January-March).
2. For Public Procedures and Application Documents
There are surprisingly many scenes where you are asked to fill in the Japanese calendar, such as "Reiwa X Year", for government office documents and year-end adjustments. You can instantly confirm conversions like "2026 is Reiwa 8".
3. Check for Longevity Celebrations and Bad Luck Years
It can also be used to check longevity celebrations such as Kanreki (60 years old), Koki (70 years old), and bad luck years. It is also convenient when checking the age of family and relatives.
Useful "Japanese Calendar Conversion" Rules to Remember
I will also introduce simple mental arithmetic techniques for when you cannot use the tool.
- Reiwa (2019-): Subtract "18" from the last 2 digits of the Western calendar (Example: 2026 - 18 = Reiwa 8)
- Heisei (1989-): Add "12" to the last 2 digits of the Western calendar (Example: 2018 + 12 = Heisei 30)
- Showa (1926-): Subtract "25" from the last 2 digits of the Western calendar (Example: 1980 - 25 = Showa 55)
However, for document creation where calculation errors are not allowed, it is certain to check with a tool after all. Bookmark it so you can open the Age Chart anytime you need it.
