The sixth 節気 “sekki” division of the traditional Japanese calendar is:
穀雨
(こくう)
“kokū”
‘grain rain’ (solar term)
The second “kō” microseason within this division is:
霜止出苗
(しも やみて なえ いずる)
“shimo yamite nae izuru”
Last frost, rice seedlings grow
That makes 霜止出苗 the seventeenth microseason of the year!
It typically lasts 25~29 April.
