Quiet hours: why the clock is silent at night
Yes — Horologe is silent from 10pm to 8am by default, and it's $5.99, paid once. You can move those hours, turn the quarters off, or right-click the bell in the menu bar to silence it immediately.
The specification, in prose: four faces — Mantel, Station, Chronometer, Nocturne; five bells — Westminster, Whittington, Ship's Bell, Temple Bowl, Grandfather; the quarters on or off, and the hour counted out either way. Quiet hours are on by default, and adjustable. A right-click on the menu-bar bell mutes everything from that moment. It weighs about three and a half megabytes, needs macOS 15 or later, and comes from the Mac App Store.
Why ten and eight
A clock in a bedroom is a negotiation. Anyone who has lived with a striking clock has either silenced it or learned to sleep through it; quiet hours are the software version of that bargain. Ten at night is late enough that the day is over for most rooms. Eight in the morning is early enough that the day has started without the clock having to announce it.
Those are defaults, not rules. If you work nights, move them. If the clock lives in a study and the bedroom is down the hall, shorten them. The point is that the quiet is the clock's default state at the hours when a bell is least welcome, not a switch you have to remember.
What quiet hours actually do
They hold the sound. The clock keeps its face and keeps the time; it simply stops speaking until the hours pass. If you want the hours alone, turn the quarters off and leave quiet hours where they are. If you want the quarters during the day and silence at night, that's the same setting doing both jobs.
The menu-bar mute is separate, and faster. Right-click the bell in the menu bar and it's silent from that moment; the bell goes struck-through so you can see that it is. There's no panel to open and no switch to find. That's deliberate, because the moment you most want silence is the moment you least want to go looking for a setting.
What it can't do
It can't know you're on a call. Horologe doesn't watch your screen or listen at your microphone, so it can't tell a meeting from an empty room. That's the trade: a clock that's deaf to your calendar, and one right-click from silent. Quiet hours cover the same stretch of every day without you thinking about it; the mute covers the exceptions.
If you're setting it up for the first time, the advice is the same as everywhere else in this journal: Grandfather, hour only, volume low. Choosing a chime explains why that's the easiest voice to live with. The honest answer about annoying clocks is the longer version of the objection this post is answering.
Horologe is $5.99 once, with quiet hours already on. For the menu-bar side of the same idea, read the menu bar clock and the clock behind it.
