Timing a Session Against the Closing Hour

Closing time is not when a cafe closes; it is when it stops being usable. Music goes up, the floor gets swept, tables around you get wiped, and the last order was called twenty minutes ago. In practice you lose the last thirty to forty-five minutes of any posted opening hours, and more in small rooms.

So plan backwards. If you need three hours, you need a place that closes at least three and a half hours after you arrive, and you should know the number before you sit down rather than discovering it when the chairs go up. The same applies to the reverse: arriving at opening is often the best hour of the day, quiet and fully stocked, and it is the hour almost nobody uses.

The midnight problem

Watch for rooms whose closing time is after midnight, because a naive reading of hours breaks there — a place open until two in the morning has a closing hour numerically smaller than its opening hour, and plenty of listings, apps and homemade filters get that wrong and show it as closed all day.

This site calculates open and closed in your browser and in your timezone precisely because of that class of error, including the after-midnight case. It is a small thing that matters mostly to two groups: people working late, and people reading a page about a city they have not arrived in yet.
