It's time for tea now; but the child (13)
This little line locates us very specifically in time (it's not just autumn—it's tea time), and it's a pretty cool contrast with the "bigger" sense of time we have from the mention of September and failing light.
Time to plant tears, says the almanac. (37)
Well isn't that such a strange declaration of time? Is this what the almanac "foretold" earlier in the poem? And what makes that moment "time to plant tears?" We didn't know that was a thing people planned for.
