The International Days are an opportunity to highlight important causes and topics, but also diseases or disorders that we do not talk about enough (hemophilia, anosmia, Angelman Syndrome). And then there are the unlikely days: those of scrapbooking, nude gardening (yes, yes) or emojis.

Next to birthdays, business meetings and (future) family meals, you can indicate the World Days that concern or speak to you. And for that, there is no better medium than the 2021 calendar.

World days month by month

In total, more than 500 World Days are listed by the site dedicated to them. We have put them together for you.
