It's been prompted by the fact that the UK and the US (and a lot of other countries apparently) celebrate today yet we Aussies wait until the first Sunday in September to pay tribute to the Old Man.
It doesn't even align with Mother's Day, which we celebrate on the second Sunday in May (same as the US) almost 2 months later than here in the UK. It's mighty confusing. And in pondering this very issue out loud with my hairdresser yesterday, I made a pledge (she did have scissors in her hand at the time) that getting to the bottom of this sticky question would be my priority for the remainder of the weekend.
Father's Day is a relative newcomer to the 'holiday' calendar (although who gets a holiday?) first appearing in the USA 102 years ago when, following a sermon in Spokane in 1909, a young parishioner, who had lost her mother in 1898, asked for a way to honour her father. Originally suggesting her father's birthday, the 5th June, the eventual date was set for 19th June 1910. And whilst Father's Day was born, it took until 1972 for it to take hold when Lyndon Baynes-Johnson declared the third Sunday in June a national holiday.
The third Sunday in June is the Father's Day of choice for many countries - USA, UK, India, Canada, China, France, Greece, Hong Kong, Pakistan, Singapore, South Africa, Sri Lanka, Switzerland and Turkey. But other countries choose different dates to honour fatherhood. Russia celebrated on 23rd February this year and Thailand will take its turn on the 5th December. Spain, Belgium and Italy celebrated on the 19th March, Germany on May 17th (always on Ascension Day the Thursday forty days after Easter) and Sweden will on the second Sunday in November. South Korea had Parent's Day on the 8th of May (so one day for all parents instead of two separate days) and Brazil will celebrate the day of fathers on the second Sunday in August.
You can see why expat life can be very confusing.

So to my old man, hope you have had a brilliant Father's Day (in-waiting).
