classic waka stream

Though I would regret
Yet this day that ends the spring
Has come at last now—
Even to the evening hour
Of this final day of spring.

Meaning
Though I regret the passing of time, the day that marks the end of spring has come at last, even to its evening.
Commentary
91. The End of Spring

There was a man who grieved deeply even over the passing of days and months.
The poem was composed by that man around the end of the third month.

Even if the days pass without any special event, once they are gone they never return, and one only grows older. The poem may be lamenting this quiet sorrow.
