I heard yesterday on the weather report that the sun will not set before eight p.m. from now until August 18. It’s a good way to celebrate May Day and the start of a new month, with the promise of light.

Hot autumn days with an unshakeable air of melancholy are proof that it’s not lack of warmth that makes me mourn the end of summer. It’s the early darkness.

Extra daylight means early mornings and late nights. It means tomatoes and zinnias and basil. It means after-dinner strolls,  evening swims and long suppers on the deck. And of course, it’s the perfect excuse for insomnia. Summer is often thought an indolent time, but when you consider the extra daylight it gives us, it’s better thought of as an active season, a heroic season.

Knowing we have three and a half months of late sunsets ahead of us gives me a sense of calm — even after solstice comes, we will still have light on our side.
