Usage Notes

按时 is an adverb placed before the verb it modifies. It emphasizes adherence to a specific scheduled time. It differs from 及时 (in time/promptly), which focuses more on acting before it is too late. 按时 is about following a set schedule.

Memory Hook

按 means "according to/following" and 时 means "time." So 按时 means "following the time": sticking exactly to the schedule.
