spring day (long and quiet)
Archaic literary noun for a spring day that feels long and peaceful. Not used in modern everyday Japanese; found in classical poetry and prose.
In the garden on a long, quiet spring day, the sound of birds echoes.
Compound of 春 (spring) and 昼 (daytime). The reading しゅんちゅう is the on'yomi of both characters. The exact historical origin is uncertain, but it follows a classical Chinese-derived pattern for poetic seasonal terms.
