Pro Tip

Distinguish from '滞留時間'

While both refer to waiting periods, 滞留時間 (tairyū jikan) often implies a more passive or enforced delay (e.g., traffic congestion), whereas 待機時間 emphasizes readiness or preparedness during the wait.

Gold Rule

Context matters

Use 待機時間 for periods where the subject is actively prepared to act (e.g., a doctor on standby), but use 滞留時間 for unavoidable delays (e.g., a delayed flight).

Word Origin

Composed of 待機 (taiki, 'standby/waiting') + 時間 (jikan, 'time'). 待機 is a Sino-Japanese compound meaning 'to stand by' or 'to wait in readiness,' derived from Chinese 待機 (dàijī). 時間 is a Sino-Japanese term for 'time,' also from Chinese 時間 (shíjiān).

Usage Notes

Commonly used in both everyday contexts (e.g., waiting for service) and technical fields (e.g., computing, manufacturing). In business, it often refers to idle time between tasks or processes.
