The story of Haruko
Japan switched from a lunisolar calendar to the Gregorian one in the middle of a month. The government announced in November that the third day of the twelfth month of the fifth year of Meiji would instead be the first of January eighteen seventy-three — so that December had two days and then stopped. Part of the reasoning was diplomatic and part of it, as the officials involved admitted afterwards, was financial: the old calendar had a leap month due the following year, which would have meant paying thirteen months of salary to a newly created bureaucracy the treasury could not afford. The change also moved every festival. Some were kept on the same numbered date in the new calendar and now fall a month early relative to the seasons they were about, which is why some places celebrate the same festival twice.

spring child
The sound haru is most often written with the character for spring, and read that way the name is straightforward. Several other characters share the sound and carry different senses, and the romanised form cannot tell you which a particular family used.

Three syllables, all short and even. Japanese does not stress syllables the way English does, so an English speaker will add one; putting it lightly on the second is closest.

Fashion outlook
Haruko sits outside the current charts, and that is its own kind of answer: naming cycles can only date the names they carried up. A name this rare has no decade stamped on it — it cannot go out of fashion, because it was never in.

The trade-off
- Every syllable is open, so English speakers manage it on a first attempt.
- Haru works as a short form and is a real name in Japanese on its own.
- The spelling is unambiguous and cannot really be misspelled.
- The ending places the name in a specific generation and is now rare in Japan.
- The romanisation throws away the characters, which are where the meaning lives.
- Haruka and Harumi will both be confused with it in speech.
