日 is read ひ (sun) and 陰 is read かげ (shade), so ひかげ joins them: the shade that sunlight leaves behind. Trees and buildings create it.

日 is a pictograph of the sun, originally drawn as a circle with a dot or stroke inside representing the sun's substance. Over time the round shape was squared off into the modern rectangular form. It means 'sun' and by extension 'day'.
