Curiosa Day is a small hobby project of mine, where I gather interesting and lesser-known observances held around the world. It is published daily in the form of two different newsletters. One of them contains a list of observances for the current day (“Calendar“) and the other one (“Days“) contains a short article/explanation about one of the observances of the day.

Since the two newsletters are related but different they are sent as two different emails. If for any reason you are bothered about receiving two emails instead a single one, Substack made our life easier providing a way where one can switch selectively on and off for any section without unsubscribing from Curiosa Day altogether.
