When did Half-Birthdays become a thing?

So DGS2 "graduated" from being in nursery into his pre-school year - when did that become a thing ?

Never heard of a half birthday. DH moans if someone celebrates 55, 65, 75, 85 but he is miserable!

With my cynical sense of humour I would give them half of a £50 note or gift coupon and the other half on their real birthday.

I’ve never heard of it.
But three of our grandchildren are winter birthdays, and we’ve gotten into the habit of having a big party in the summer with a hot tub and bouncy castle, and making a big thing of it.
So, yes not a bad idea in some circumstances.

Quarters, halves and three-quarters of the year matter to the very young and the very old. Time goes so slowly for the former and far too fast for the very old. My late mother-in-law always included the quarter when she was 92 and asked her age.

Never heard of it either and it ll go back where it came from back of the queue utter nonsense

I knew a little boy whose birthday was Christmas Day and he always had a party with his school friends for his half birthday in June.

I suppose once you start getting old maybe you have a half birthday in case you don't make it to the next one!

When I was a young girl I would say I was
‘13 and 1/2’ or even ‘3/4’, as I so much wanted to be older!

Never heard of it, how odd!

I suspect HG it’s a question of not tempting fate…?

My daughter and one son both have January birthdays.

To enable us to have outdoorsy type birthday parties, we used to celebrate their half-birthdays in the summer. It also meant that they didn't have a lot of additional presents just after Christmas.

They don't do half-birthdays now though (both in their 30s). That stopped when they were about 11 or 12 and wanted just a few select friends to go to the cinema or bowling, and have a burger afterwards.

Celebrating half-birthdays in later years just seems odd!

Never heard of it ... no doubt will have cards eventually out to celebrate !!! If they do another waste of money, no I won't buy any !

The birthday of my younger Gdd is on 6th January, so I’ll be giving her a little half-birthday present when it’s her big brother’s birthday next week.
I will also be giving a little something to elder Gdd (April birthday) - can’t very well do one without the other at their ages.

My friend's birthday is on Christmas Eve so I always send her a "half" birthday card in June so that she can really appreciate it.

Half birthdays ????
What the heck !

My granddaughter told me recently it was her eight and three quarters birthday. I thought it cute, it will help her understand how long a year is.

I’ve know a few older people (over 75) do it - makes sense doesn’t it…?
