# Quiet hours

> One nightly window where only your most important alerts still notify.

Web page: https://infrainbox.app/docs/notifications/quiet-hours/

One window, for the whole workspace. During it, a notice below a destination's own quiet-hours threshold is held back — each destination sets its own threshold on its edit form.

Open **Notifications → Quiet hours** (dashboard screen `/rules/quiet-hours`) (owner or admin to change it; every member can see it).

## Setting the window

Turn it on and set a **From** and **To** time, in the workspace's own time zone. A window that runs past midnight (`23:00` to `07:00`, say) is fine — it's read as one night.

Once you change something, a save bar appears at the foot of the page; **Save** confirms with **Saved** and an **Undo** that puts the previous window back.

## What it does, and doesn't, hold back

- **Held, not lost.** A notice held by quiet hours isn't sent late once the window ends — the inbox already has it, and nothing arrives after the fact to surprise you in the morning.
- **A destination's own threshold decides who still hears what.** Set a phone's threshold to CRITICAL and a Slack channel's to WARNING, and the phone stays quiet for things the channel still posts.
- **Recoveries and corrections still go through, silently.** If a destination was already told about an incident, quiet hours never leave it looking wrong — a resolve or a state correction for that incident still updates it, just without a sound.
- **A test always goes through.** Sending a test from a source or a destination bypasses quiet hours entirely, on purpose — it exists to prove the destination itself works.
- **Your phone's own Do Not Disturb or Focus mode still applies on top.** Quiet hours can't override those; they only decide what InfraInbox itself sends.
- **Daylight saving isn't special-cased.** The window is wall-clock time, so a night that crosses a clock change runs an hour shorter or longer, like any other alarm set by wall-clock time.
