Explanation

  • An expression used as an excuse or explanation for being late or forgetting something due to being deeply engrossed or absorbed in an activity.
  • Implies that focus on the activity caused unawareness of the passing time.

Origin

  • Figurative language where time is conceptualized as something linear or quantifiable that can be monitored or 'tracked' (like following a path or keeping score).
  • To 'lose track' means to lose one's place or awareness of this progression.
  • A common, standard English idiom.

Alternatives

Slang/Informal:

  • Got sucked in (by an activity/show/game)
  • Was in the zone (Focused intently)
  • Time flew by / Time just slipped away
  • Got sidetracked (If distracted by something else)

Vulgar/Emphatic (Expressing frustration at the consequence, i.e., being late):

  • Fuck, I totally lost track of time!
  • Shit, look at the time! I lost track.

Milder/Formal:

  • I became engrossed in my work/reading and failed to notice the time.
  • My apologies, I was preoccupied and didn't realize how late it had become.
  • I regret that I was not more mindful of the time.

Situational Appropriateness

  • Informal to semi-formal.
  • A common and generally acceptable excuse for lateness caused by engrossment, especially in social situations or for minor delays at work.
  • May not be sufficient for significant lateness in very formal or critical professional settings without a more substantial apology or reason.

Misunderstanding Warnings

  • Generally clear.
  • Non-native speakers should understand it implies being *absorbed* in something, not simply being generally unaware or careless about time management (though people might use it as an excuse even if they were just disorganized).

Examples

  • We were having such a fascinating conversation, we lost track of time and missed the last bus!
  • I got sucked into that video game and lost track of time; suddenly it was 2 AM.
