Etymology
昶 combines 永 (long, perpetual) with 日 (sun, day), suggesting a long or clear day. The exact historical development is uncertain, but the component combination fits the meaning.
Meaning mnemonic
The sun 日 sits inside the idea of something long and flowing 永, like a day that stretches on endlessly under a clear sky.
Reading mnemonic
For チョウ, imagine a long, clear day stretching out like a 蝶々 (ちょうちょう, butterfly) gliding through the sunlight: チョウ from ちょうちょう cues the reading.
