Day Moon began in the winter of 2020 as a home-baking pop-up during the pandemic — first loaves out of a home kitchen, a Venezuelan pan de jamón collaboration before Christmas.

Founder Wendy Williams trained at Tartine before striking out on her own. In 2021 the bakery became a Sunday stand at the Clement Street Farmers' Market, where it built a regular following for two years before opening on Irving Street in the Outer Sunset in 2023.

The market stand is still there on Sundays — same loaves, same scones, in the neighborhood that started it.
