long day, extended, relaxed
昡 centers on a day that feels long and stretched out, giving a sense of leisure or unhurried relaxation.
昡 combines 日 (sun/day) with 玄, which likely contributes the sound and may suggest something deep or prolonged. The exact historical development is uncertain.
The sun 日 stays out for a long, extended day, and the right side 玄 looks like a stretched-out thread, reinforcing the idea of a relaxed, drawn-out day.
For ケン, imagine a long, relaxed day spent with a friend named Ken: Ken -> ケン, and the sun stretches the day out.
