How it's used

Focuses on the repetition of an action within a short, predictable cycle, such as daily routines or hourly tasks. While often interchangeable with 定期, the latter implies a longer, more formal interval like monthly or yearly, whereas 定時 suggests a recurring habit within a single day.

Common mistake

Avoid using this to describe a one-off scheduled event, as it specifically emphasizes the recurring nature of an action. For a single appointment, use 預約 or 指定時間 instead.
