Kairos
noun /ˈkaɪrɒs/ — The perfect moment — when conditions align for something decisive.
Definition
The right or opportune moment; the supreme instant when conditions align perfectly for decisive action. Distinct from chronos (sequential, clock time), kairos is qualitative time — the moment that matters.
Beyond the definition
Kairos is why some moments feel larger than they are. Not every second is equal. There are moments when the window is open — when everything has aligned and action is possible in a way it simply wasn't before. Kairos names that.
Origin & history
From Ancient Greek καιρός (kairos) — the right, opportune, or supreme moment. In Greek mythology, Kairos was the youngest son of Zeus, the god of opportunity. He is depicted with a lock of hair at the front of his head — you can only grasp him as he approaches; once he passes, there is only a bald head to clutch.

The business had been struggling for two years. The founder had been approached by three potential buyers, all too early. He had waited, against advice, until the right one appeared — the one who arrived at the moment when the market was moving in exactly the direction they'd built for.
The timing was not luck. He had spent two years refusing to mistake an available moment for the right one.
"Everyone wanted me to sell when we were desperate," he said later. "I waited until we weren't." The gap between chronological time and the right time is the whole thing. Most people don't have the patience to hold the space between them.
