How Long Until 10:00 PM?
10 PM — the adult bedtime and late-news hour
What 10:00 PM Actually Means
10:00 PM is the most common adult bedtime in the US according to wearable-device sleep data, and the traditional late local news hour on most non-network US TV stations (CBS affiliates and independents). It's when most bars in suburban US markets hit their peak crowd of the night, and when evening movie screenings typically begin their last show of the night.
For people counting down to 10 PM, it's often either a bedtime reminder, the start of a show they've been waiting to watch, or the last call window before a late-night activity (movie, bar, final train). In 24-hour time it's 22:00 — straightforward and unambiguous.
Why People Count Down to 10:00 PM
- Most common US adult bedtime (per Fitbit/Apple/Withings data)
- Late local news broadcasts (CBS affiliates, independents)
- Last movie screening of the night at most multiplexes
- Peak bar crowd time in suburban markets
- Last commuter-train departures in many smaller metro areas
Did you know?
A 2019 study of 4.7 million Fitbit users found that the single most common bedtime in the United States is exactly 10:42 PM — close enough to 10 PM that people will round down when asked in surveys, which explains why "10 PM" still tops most self-reported bedtime charts.
