Translation guide
CE is an abbreviation for Common Era, used in the Gregorian calendar to number years. In Japanese, it is typically expressed as 西暦 (seireki) when referring to the calendar system, or simply by stating the year number without an explicit era marker in some contexts. Unlike English, Japanese often uses the Japanese era name system (年号, nengō) for years, so CE years may be converted to the corresponding era year.
Referring to the Common Era calendar system as a whole, or specifying that a year is in CE rather than BC/BCE.
The standard term for the Common Era or Anno Domini system. Used when distinguishing from the Japanese era system or from BC.
Stating a specific year in CE, often when the context already makes the era clear.
In many contexts, especially when the era is understood or when using Western years is standard (e.g., in international business), simply say the year number followed by 年. No explicit 'CE' is needed.
2024年に日本へ行きました。
I went to Japan in 2024.
Use this pattern when you need to explicitly clarify that the year is in the Common Era, for example when contrasting with Japanese era years or BC.
In Japan, years are commonly expressed using the Japanese era name (年号, nengō), such as 令和 (Reiwa), 平成 (Heisei), or 昭和 (Showa). For example, 2024 CE is 令和6年. When speaking Japanese, it is often more natural to use the era year in domestic contexts. However, in international or academic settings, 西暦 is widely understood and used.
今年は令和6年です。
This year is Reiwa 6.
西暦では2024年です。
In the Common Era, it's 2024.
The abbreviation 'CE' is not commonly used in Japanese text. Instead, 西暦 is written out. In some academic or English-influenced contexts, you might see 'CE' or 'C.E.' in parentheses, but it is not standard.

the year 2024 CE
