Why Is Alarm Clock Snooze Only 9 Minutes?

While alarm clocks date back to at least 245 B.C. the snooze button only came to be in 1956, allowing people to stay in bed for an extra nine minutes, then 18, then 27 and 36 minutes. There are different theories as to why nine minutes has always been the snooze standard, from 1956 to today’s default phone settings – Apple even pays homage to it.
Quora suggests that nine minutes was the only technologically feasible solution for snoozing due to the standardized gear technology back in the day. At the time, mechanical clocks didn’t allow for specified snooze times because the alarm function was a separate set of gears that responded to movements of the hour hand.
One theory suggests that the nine-minute interval was a marketing decision, made to make people feel like they were getting a few minutes instead of oversleeping. At the time, science had proved that ten minutes allowed people to fall into deep sleep. With this in mind, clock-makers decided on the nine-minute gear, allowing for a quick snooze while potentially avoiding a grumpy wake-up.
No matter how long the snooze, alarms clocks will always be a necessary evil, parting you from your bed one alarm at a time.
