Is there an International Men's Day?

There really is, on November 19. Yet since the 1990s it has only been labelled and is not acknowledged by the UN. It's celebrated by people in over 60 countries, including the UK.

The aims of the day are "to concentrate attention on the wellbeing of men and boys, to strengthen gender relations, to encourage gender equality and to highlight positive role models for men." Theme for 2019
