Curiosa Day is the place where I gather interesting and lesser-known observances from around the world. I publish it daily in the form of two newsletters.

One is always the daily calendar, which features a list of observances for the current day, while the other sometimes is about the days (a short article or explanation about one of the day’s observances), and sometimes is just a blog post.

Since these newsletters are related but distinct, they are sent as two separate emails.

If you prefer not to receive two emails instead of one, Substack makes it easy to manage your preferences, allowing you to selectively turn sections on or off without having to unsubscribe from Curiosa Day entirely.
