That time of the years again, when parts of the world, not just rjhowie, are living in different years. New Zealand has made the transition, soon Australia's turn. Stockholm not for a while yet. 

The New Year/Division is pretty unevenly divided across the planet though.
2½ hour ago: tiny Pacific islands that have made sure to be first
1½ hour ago: New Zealand and more tiny islands
½ hour ago: Easternmost slice of Russia, more tiny islands
In ½ hour: most of Australia
In 1½ hour: Japan, the Koreas
In 2½ hours: China, Philippines
In 3½ hours: Indochina including Indonesia
In 6 hours: India
In 8½ hours: Main parts of Russia
In 9½ hours: Greece, Eastern Europe
In 10½ hours: Most of Europe
In 11½ hours: The slow parts of Europe
In 14½ hours: Brazil
In 16½ hours: East coast of North America
In 19½ hours: West coast of North America
In 20½ hours: Alaska
In 22½ hours: Hawaii
and finally some more Pacific islands

A bit excitement in hours to come, then slow (South Asia doesn't put up much of a show), OK around Europe, then the Atlantic trench, then NYC and fadeout. 

Yeah, congrats NZ and Kiribati and the rest.

Same as last new year, I am trying to find a live stream on YT that show the celebration fireworks in most places in turn. Right now I cannot decide if USA Today is better than NBC or not.

Edit: The protesters in Hong Kong cleverly stole the spotlight holding the banner "Never Going Back".

They seem to share same limited feeds. It should be possible to do better.

Anyway most of the world has entered 2020 already, and we haven't gotten to Europe yet (Russia and Turkey excepted).

It struck me that the population growth in Africa will balance this out somewhat. The Americas will still be kind of a post scriptum, but at least there will be a significant number of people left when we get to Eurafrica. It would be an East Asian spike, a South Asian spike, but the biggest spike will be Eurafrica. Yay, us.

Yes, it seemed better last year. They keep getting worse.

Even in 2020, Turkey is still not Europe.
