What’s your personal merge/deploy policy?

The other day I was touching up a PR that had been approved and was about to merge and deploy it when, out of habit, I checked the clock. It was 3:45pm, which for me, was past my “merge before" time of 3:30pm. I decided to hold off and wait until the next morning.
The whole process got me thinking. Does anyone else have their own personal merge or deploy policies? Is there a time before or after when you say, not today? Is there a day of the week you don’t like to merge stuff. A lot of people joke about read-only Fridays, but I have to admit, I kinda follow that rule. Anything remotely high risk I wait until Monday to merge.
