Thursday, friday, and saturday (fun days already, generally speaking) have the added magic of being particularly romantic. Monday? Not so much. It's not a bad day. You'll probably eat some delicious things and have fun in social settings. It's just not romantic. Tuesday and wednesday are outright annoying, featuring encounters with people who want things they aren't able to articulate. But thursday, friday, and saturday are very different. Blossoms figure in the stars, which is appropriate metaphorically. On sunday, you have a spring in your step.
