Having a bad day? Survey shows you’ll know it by 8:36 a.m.

If your Monday is already off to a bad start, chances are it all started around 8:36 a.m.: that’s when most Americans know they’re in for a bad day, according to a survey

Talker Research conducted a poll as to what constitutes a “bad day” and when it starts. 

It’s around 8:36 a.m. that 35% of people say they come to terms with feeling sick upon waking up, or that a poor night of sleep has caught up with them (31%). Twenty-nine percent says by then, they’ve already had — or are in the middle of — a headache.

If they manage to get past those, 26% say 8:36 a.m. is about the time they’ve misplaced their keys as they’re trying to get out the door — or even worse, it’s when they discovered they’ve forgotten their phone after already leaving the house (25%). 

Twenty-six percent reported that if any of those things goes bad that early, they consider the day ruined.

The survey, which was commissioned by Avocado Green Mattress, also revealed that the average person suffers four bad days per month — or a month and a half’s worth of bad days a year.
