There are many different cultures in the world, and picking when things happen is also part of the culture.
Maybe another country already has a holiday on tomorrow, so they need to move Fathers Day to a different day

Hi Bensen. Happy early Father’s Day. In America and many other places Fathers Day is celebrated on the third Sunday in June- but some places do it on different dates and some places may also or only have a holiday similar to “Father’s Day” but not the same.
“Fathers Day” started in the USA and began to get some recognition around the early 1900’s. The primary start was a young woman in Washington state who was raised by a single father and wanted a special day for him. it was A controversial holiday early on. Men were even more in control and power in society and the home than now- and many men felt it was pointless or silly to give them a special day because basically every day was about them already. Mother’s Day already existed and many men felt Father’s Day was too “feminine” and didn’t like the similarities to Mother’s Day or want gifts and flowers.

People also were upset at the commercialism of holidays and felt it was an unnecessary event to promote spending money. Father’s Day really started to gain traction around the Great Depression and World War Two. In the depression- businesses and government were looking for ways to get people spending to stimulate the economy so they tried to push the holiday. In WW2 most men went and fought- and post war the US entered a very consumerist culture so those things helped the holiday become more popular. In the United States Father’s Day didn’t become an official holiday until the 1970’s- so it actually isn’t so old a tradition but most people think it’s ancient or something.

The reason for the third Sunday in June is said to essentially be this: the young woman who got the ball really rolling on Father’s Day wanted it to be on her fathers birthday- but the USA celebrates Mother’s Day in May. So they kept the day in the fathers birthday month but moved it to the third Sunday to give the priests time between the Mother’s Day service and Father’s Day service.
People were already mostly celebrating Father’s Day the third Sunday in June by the 1970’s, so when it became an official holiday it would t make much sense to change the date, and those making the decree also factored in that having some time between Mother’s Day and Father’s Day to allow mental and economic recovery was probably a good idea.

In Australia they observe Father’s Day the first Sunday of September. Why? Well… there isn’t really an answer that I know of. There are some theories and a common story about Australia finding out about the holiday “late” and not wanting to wait to the next year so holding in September- but historical newspapers and writings pretty much debunk that as a myth. So no one is entirely sure as far as I am aware why Australia does the first Sunday in September. NZ also celebrates the first Sunday of September as well. This dates back to around the 1930’s. The prevailing theory is that when the holiday was introduced there wasn’t the same desire to try and keep it in some strange Americans birth month, so it was moved to September to give more distance between it and other holidays around the same time for commercial and other reasons. In Scandinavia it is often celebrated in November and this is likewise believed to largely be to distance Father’s Day from other holidays.

Now- “Fathers day” in the branded sense came from the USA from Washington state- but there actually was an earlier recorded observance of a “Father’s Day” in the USA from the opposite coast after a coal mining incident- it did not however catch on the way the Washington Father’s Day did.
And as said earlier- similar holidays pre date “fathers day” and are essentially similar in concept. Since at least 1508 there have been religious celebrations in Catholic Europe to celebrate fathers and or forefathers. I won’t go deep here because there are LOTS of holidays called “foreFather’s Day” or feasts of forefathers and so forth and not all are the same or related to Father’s Day in concept. Many celebrate specific ancestors such as those ancestors of Jesus according to their religious texts or certain saints etc. but certain of these holidays going back to 1508 did always or often include a general celebration of fathers, grandfathers etc.

Some cultures skip “Father’s Day” and instead do a “parents day” in which any and all parents are celebrated on the same day. South Korea is one country which has “parents day.” So there is some specific info that is still a bit general on the subject. Creativedragonbaby summed it up best really- the exact specifics and dates etc. of Father’s Day and how it is celebrated or if it is and so forth vary by culture and place or time. Not all “Father’s Day” type celebrations are related either. The dates chosen most often have more to do with practical concerns than any significance- the distance from other holidays, and perhaps depending on local traditions or intent of how to celebrate- some mind to the weather. In the USA for example- most of the country has “outdoor weather” into late September-

June isn’t known broadly as a rainy month and most places is far too early for snow fall and such temperatures. It may be hot, some places more than others, and most of the USA is in summer around the end of June. in the USA this is largely coincidence- our celebration traditions of Father’s Day adapted to include things like Father’s Day bbq or grilling because it happened to be in a month that was general pretty suitable for outdoor activities most places and a month where it is common for children in the modern day to be on their summer break from school. As envisioned originally there wasn’t anything particularly outdoorsy about US Father’s Day- and early on church would have been one of the places mostly used for celebrating the day since it was on a Sunday.
Of course Father’s Day found it’s way outside of a religious base and became a holiday for all religions and those who don’t have religions.

So yeah. That’s about what I have.

You are so cool- you should be an author! Your writing is so easy to read and lots of fun too!

Lol. Thank you Bensen, I think you’re cool too and enjoy seeing and reading your posts and updates.
