โฐ Time is a funny thing! For starters, how are we already nearly in August?

But more importantly, when examined closely, time reveals several excellent #geoweirdness examples. In this week's thread, weโ€™ll look at some of the weirdest timezone quirks from around the world.

To get us started hereโ€™s a map of the world as segmented by the tz database.

2/ Before we go full #geoweirdness , a bit of #geoeducation

Time zone information is tracked by the "tz" database, a fascinating, open-source project worth learning about!

en.wikipedia.org/wiki/Tz_datab

Most countries have simple time zones, generally based on the sun's position relative to the region's positions on the Earth's surface. However, time zones also involves political and historical factors, and thus they don't always correspond to the longitudinal lines on the globe.

3/ Let's get into the #geoweirdness

We start with countries where the time zone doesnโ€™t fall on the hour, usually changing with increments of 15 minutes.

Examples include Chatham Standard Time (UTC+12:45) and India Standard Time (+05:30).

Time in India ๐Ÿ‡ฎ๐Ÿ‡ณ is worth a thread in itself, though. For example, Bombay Time (+4:51) was used in 1884 (!) and is still used by some Parsi fire temples in Mumbai.

4/ Some countries like China ๐Ÿ‡จ๐Ÿ‡ณ use a single time zone (UTC+08:00), regardless of geography.

This timezone makes sense for Beijing, but not for western territories of the country. This leads to the odd situation that when you cross the border from China to neighbouring Afghanistan ๐Ÿ‡ฆ๐Ÿ‡ซ you change time by 3 hours and 30 minutes.

5/ Other "wide" countries like the US ๐Ÿ‡บ๐Ÿ‡ธ have multiple time zones. Local rules can lead to all sorts of #geoweirdness

Consider Arizona. Due to sunny climate, the state does not observe daylight savings time. Except of course within the Navajo Nation, which thus has a different time from the rest of the state for half the year. But of course the Hopi Reservation, an enclave within the Navajo Nation does follow DST. So you change tz six times by taking Route 264!

6/ Equally odd is the US ๐Ÿ‡บ๐Ÿ‡ธ state of Indiana. Most counties in the state use Eastern Time, UTC-05:00.

Emphasis on the word "most"! 12 of 92 counties, however, observe Central Time, meaning their inhabitants are one hour behind their counterparts.

Even more interestingly, these counties are split in opposite corners of the state.

7/ There are some places on Earth where three time zones meet in a single point.

The most well known spots are possibly in ๐Ÿ‡ฆ๐Ÿ‡บ Australia's outback.

Readers who enjoy a bit of postcode madness with their time zone oddities (who doesn't) will particularly enjoy Australian postcode "0872" which spans multiple timezones as it covers parts of South Australia, Western Australia, and the Northern Territory.

8/ Time zones and especially DST rules change frequently. And sometimes with only minimal notice!

Last year there was major confusion in Lebanon ๐Ÿ‡ฑ๐Ÿ‡ง due to last-minute (pun intended) disagreement as to wether to follow DST or not.

In 2011 Samoa ๐Ÿ‡ผ๐Ÿ‡ธ shifted from one side of the International Date Line to the other, skipping the entire calendar day of Friday, 30 December 2011 in the process

9/ Time can be a very political.

Spain ๐Ÿ‡ช๐Ÿ‡ธ currently uses Central European Time, a change made by dictator Franco in 1940 to align with Nazi Germany. The change was never reverted and has become subject to much debate.

Some feel this causes Spainโ€™s โ€œlate-night culture,โ€ and are pushing for a change to boost productivity.

Portugal ๐Ÿ‡ต๐Ÿ‡น actually switched to CET in the early 90s but then reverted due to public dissatisfaction

10/ Antarctica sits on every longitudinal line and thus in theory uses every time zone.

In practice each research station chooses a timezone to use.

11/ โŒ›Timeโ€™s almost up on this thread (sorry ๐Ÿ˜‚).

As members of the geosphere will be well aware, geo extends far beyond cartography and mapping.

As the saying goes "Everything happens somewhere", but the next question is usually "When?" Which is precisely why we return timezone information as an "annotation" in our geocoding API results

12/ We hope you enjoyed our look at the #geoweirdness of time zones ๐Ÿ•˜๐Ÿ•ฅ๐Ÿ•ข.

Thanks for reading and sharing. What other strange time zone examples did we overlook?

We have many more threads about specific countries and regions, border disputes, geocoding, etc over on our blog, enjoy
