We don't have an international authority or governmental remit to declare any officially celebrated "national Best Friends day". We only aim to programatically reflect what 'National Day' it is based of what The Internet Says It Is. We believe this is much more fun as it reflects the nature of how the most amusing / interesting national days are often created organically and grow based off popular social trends and sharing, as such we don't add new days to our database unless they are organically observed on social media.


Is it National Best Friends Day Everywhere?

Yes? No.. Sort of | Maybe ¯\_(ツ)_/¯

What's really intersting is how whilst some National Days like National Daughters Day are seemingly celebrated internationally irrespective of geography, some very popular days (That often become the No. 1 National Day on our homepage) are in fact locally very specific and are offical holidays celebrated on a Country's national calendar. Take National Rambutan Day for instance, Rambutan is a popular Souteast Asian fruit and not seen so much in the UK, Europe or the USA. Some regionally specific trends subsequently become immensely popular internationally and worldwide, partly fuelled by widely shared 'National Days', National Pabebe Wave Day being one such example.
