In Thailand the current year is 2566. They use a Buddhist system for some things like booking plane tickets and the Gregorian calender (2023) for others as you can see in this movie release billboard.

Having a totally different system to the majority of the world means the Thai population need to adapt and run parallel systems. This is a huge advantage for the brain but has obvious complications. But perhaps the most important point is that Thais can see a different system whilst people in Europe, the Americas and rest of Asia running a Gregorian system think that its 2023 and nothing else.

I get fiat/bitcoin system feelings about this as most of the world thinks fiat and money printing is the only system. Just as travelling to Thailand helps to understand its 2566, maybe people need to 'travel' to #bitcoin world and explore, understand and use it.
