The date sets the solar term
The tool reuses the site’s solar-longitude term calculation and compares actual transition instants. A date alone is sampled at 12:00 in Asia/Shanghai. On a transition date, morning and evening may belong to different terms.
An original arrangement
Layered petals, leaves, stems and paper fibres make a seasonal botanical illustration. The actual solar term changes the paper temperature, botanical colour treatment, scale and angle as original art direction. The image is not a forecast of actual flowering, climate or local plant conditions.
Make a dated keepsake
Dates from 1902 to 2099 are supported. The computed term, chosen date and up to 40 characters of inscription remain on the saved PNG. No location, photo or account is required.
