Age Chart

The Age Chart tool is a web application that displays both regular age and zodiac age, birth years, Japanese era names (wareki), and Chinese zodiac animals for each year relative to a specified reference year. Simply enter a reference year to instantly generate a chart covering ages 0 to 100.

"Zodiac age" (where age increments by 1 on January 1st regardless of actual birth date) is crucial for Japanese life rituals such as Shichigosan or Coming of Age Day, as well as official procedures. This tool displays both regular and zodiac ages side by side, so you can instantly check whichever is needed for your situation.

Japanese era names include Meiji, Taisho, Showa, Heisei, and Reiwa, and each year shows its corresponding Chinese zodiac sign. Hover over any zodiac sign to see information about its cultural characteristics and personality traits.

A search filter lets you quickly find a specific birth year. The CSV download feature allows you to import the table into spreadsheet applications for further analysis and processing. All calculations run entirely in your browser, so no personal information is ever sent to a server.
