Comparing with Similar Grammar Points

• 〜間に (〜あいだに): This also indicates that something occurs during a period; however, it is often used to indicate a specific time when an action took place, rather than emphasizing the idea of taking advantage of time like うちに.

Example:

• 夜のうちに宿題を終わらせておく。 (Finish your homework while it’s still night.)
• 夜の間に宿題を終わらせておく。 (Finish your homework during the night.)

Differences:

• うちに focuses on performing an action within a certain period or state.
• 間に places emphasis on the timing of an occurrence during a specified duration.
