Most holidays, Christmas, Easter, Halloween, Valentines Day are spread accross Winter, Autumn, Spring. I’d like to propose we go out all out and start celebrating a new holiday with mid summer themes on the 21st of June.
Make it a Bank Holiday, the day of the week will change each year which keep things interesting. Medieval sun can be the mascot:
People can build a model stone henge in their houses out of jenga. Party goers can get smashed throughout the shortest night of the year and wait for the sun rise. Kids can be taught some astronomy.
Not really thought out what solar food people could have but water melon or themed ice lollys or something could work.
think a non-religious Ramadan and Eid set-up would be class to adopt. a whole month where something else takes a higher priority than work, for more or less everyone, and then a big three day party at the end.
Also replace new years with nowruz, it’s better to have it in the spring than the middle of winter
Maybe the British can do something similar for their favourite homegrown foodstuff, e.g. celebrate the first English strawberry of the year, or the first Welsh leek, or the first Scottish [insert Scottish vegetable]?
