"Old" Isn't Really That Old
People in the states consider things like houses build within the last 100 years as old, but in reality that actually isn't true. Houses in other countries could have been built within the last 200 years and are still liveable and updatable. Something built within the last century is actually viewed as somewhat modern.
Writing The Month First
America is the only country that writes out the date starting with the month. June 2, 2020, isn't custom in other countries. They write 2 June 2020. For whatever reason, we just won't conform.
