Early is on-time. On-time is late.
Early is on-time. On-time is late.
We consider it impolite, if you show up for an invitation at someone’s home before the time you were invited for. Many would say it is even impolite to show up less then 5 minutes late, and consider being 10-15 minutes late the best, and up to 30-45 minutes acceptable.
For a business appointment or doctor's appointment, where there is an assistant that opens the door and a waiting area, it's expected to be early, so that you are already in front of the correct room when the appointment starts.
I don't know if it's a Korean thing or my mom-specific thing but she had very strong opinion about being early. For her 15 minutes early == on time. To reinforce this notion, she would set the house clocks later by some random undetermined minutes. The clocks in her home would all differ slightly so you could never tell what time it actually was unless you looked at your phone but you'd know you're little bit early to things for sure. Good times.
"Early is on time, on time is late, and late is unacceptable" was drilled into me while doing Civil Air Patrol back in secondary school (high school) and I habitually set all my clocks 5 minutes ahead, still, to this day.

I strive to be on time for work things, but don't mind being a little late to parties -- and this drives me and my my wife nuts, because my wife wants to be on time for parties.
Being late is not simply a property of the clock time but also of the society you are part of.
In England arriving early for a dinner party is going to get you at least a dirty look, arriving half an hour late just means that you might miss a pre-dinner drink. In Norway, if you are ten minutes late the host might send out a search party.
In a Western business context, "late" comes about 1-2 minutes after the meeting starts.
One boy took it to heart and is very prompt.
The other, eh, not so much. He was almost late to his own wedding.
