KanjiJLPT N5
Interval

interval, space

Mnemonic

A colossal gate stands shut, but through the narrow crack between its massive doors, the sun sends a searing beam of light straight into your eyes. That blazing sliver is the interval — the luminous gap where time and space converge between two barriers. You can measure every interval of your day by how the sun drifts across that slit.
Additional thoughts
Picture the kanji literally: the sun (日) trapped inside a gate (門). The gate frames the space, and the sun fills it with light, defining the interval between the doors.
Quick recall
The sun glowing through a crack in the gate reveals the interval between its doors.
