Overview
I had the opportunity to convert Japanese calendar dates (wareki) to the Western calendar using the calendar conversion service of HuTime, a temporal information analysis software, so this is a personal note for future reference.
Conversion Example
Enter a Japanese calendar date in the {wareki date} placeholder below.
For example, for “Keio 4, September 8” (慶応4年9月8日), the URL is as follows.
Other Usage
Detailed explanations are available at the following link. Please refer to it for parameter specification methods, etc.
Summary
I hope this serves as a useful reference for using the HuTime Web API.
I also extend my gratitude to the developers of HuTime for creating such a valuable tool.
