和暦

1. Origins, structure, and basic meaning

• Structure: 和暦 is read as われき and is a noun for the Japanese era-based system of expressing years and dates.
• Basic usage: Use 和暦で書く for the notation method and 和暦から西暦に直す for conversion to Western-year notation.

2. Common pitfalls and similar expressions

• Date and notation system
  • The same date can be written by Japanese era or Western year; converting the notation does not change the actual day.
• で and から…に
  • で marks the format used on the application, while から…に marks the source and target systems of conversion.
