Yet Another Timezone Tool

Type a time the way you'd say it, and see it in every place you care about.

15 sf            3 pm in San Francisco, shown in all your locations
15-17 sf         a two-hour window
tomorrow 9 utc   tomorrow at 09:00 UTC
thu 17 et        next Thursday, 17:00 Eastern
lon              what time is it in London right now?

Made for the moment on a call when someone in New York asks "would 3 to 5 my time work?". Type 15-17 nyc, read your own hours off the screen, paste the whole line into the chat for everyone else.

Quick start

1. Install the extension and open Raycast.
2. Type Convert Time and press Enter. You'll see the current time in a handful of starter locations: UTC, London, New York, San Francisco and Tokyo.
3. Type 15 sf. Every row now shows 3 pm San Francisco time in its own zone, and the line above the rows confirms what was understood: Tue 1 Sep · 15:00 San Francisco.
4. Press Enter to copy the selected row, or ⌘Enter to copy the whole list as one line, ready to paste.
5. To change the locations, open Manage Locations (or press ⌘⇧M from Convert Time).

What to type

Start with a time. Add a place, an end time and a date as you need them, in any order.

Type this	To see
15, 15:30, 3pm, 1530	that time today, in your default zone
15 sf or sf 15	15:00 in San Francisco
15-17 sf	15:00 to 17:00, San Francisco time
15 sf 2h, 15 sf 90m	a window of that length
tomorrow 15 sf, thu 15 sf	another day
29 oct 15 sf, 2026-10-29 15 sf, 29/10 15 sf	a specific date
15 utc+2	a fixed offset
sf	the current time in San Francisco
(nothing)	the current time everywhere, ticking

A bare number is 24-hour, so 7 is seven in the morning; write 7pm for the evening. Ranges follow the same idea: 7-9pm is 19:00 to 21:00, and 11-1pm is 11:00 to 13:00.

A place can be any of these:

• one of your locations, or just the start of its name: san, new york
• a code: LON, SFO, NYC, JFK. Cities pick up their airport and UN/LOCODE codes automatically, and you can add your own aliases in Manage Locations
• a zone abbreviation: cest, pt, est, ist, z
• a zone name: Europe/Berlin, Pacific Time

Your own locations are checked first, then a built-in list of 140,000 places, then zone names. That's why cst means Chicago, until you add a Chinese city and your list wins. When a word could mean two things (s could be San Francisco or Seattle), the header says so and asks for another letter.

Dates matter more than they seem: Europe and North America switch their clocks on different weeks, and for that week "same time next Thursday" is off by an hour. thu 17 et gets it right.

Reading the rows

Each row is one location, sorted west to east.

• The coloured dot shows whether that's a reasonable hour there: green for 9–18, yellow for the shoulders (7–9 and 18–21), red for the middle of the night. The hours are yours to change.
• The time or window, right-aligned so the column is easy to scan.
• The zone abbreviation (PDT, CEST).
• The offset from the place you typed (−9h). That place is marked "anchor" in its subtitle.
• A red +1d or −1d when that row has already crossed midnight.

Press ⌘I for the hour strip: one column per location, one row per hour, with your window as a band across all columns. A row where every column is green is a time that works for everyone.

Copying

Key	Copies
Enter, or ⌘1 – ⌘9	the selected row, e.g. 06:00 SFO (PDT)
⌘Enter	everything on one line, e.g. 15:00 LON (BST) = 07:00 SFO (PDT) / 10:00 NYC (EDT) / 14:00 UTC

The format is a template you can change in Settings. {time} {code} ({abbr}) is the default; {label}, {tz}, {date}, {day}, {offset} and {dot} (🟢 🟡 🔴 for the hours there) are also available. After copying, Raycast returns to its root search (there's a setting for that too).

More keys in Convert Time

Key	Does
⌘← / ⌘→	an hour earlier / later
⌘⇧← / ⌘⇧→	15 minutes earlier / later
⌘⇧↑ / ⌘⇧↓	the day before / after
⌘⇧Enter	make the selected row the anchor ("and what if Tokyo says 9?")
⌘I	show or hide the hour strip
⌃X	remove the selected location
⌘⇧M	open Manage Locations

The dropdown at the top right sets the zone used when you type a time without a place. Nudging the time or re-anchoring rewrites the search box to match (lon 15), so what you see is always what was calculated.

Your locations

Manage Locations is where you decide what Convert Time shows.

• Add (⌘N) searches 70,000 cities by name or code, another 70,000 smaller places, and every named time zone. Try Zürich, ZRH, JFK, Pacific Time or Hallstatt. For a place that's missing, add a custom place (a name plus a zone) or search OpenStreetMap from the same screen.
• Edit to rename, add aliases (zrh, zurich), give a place its own business hours, or make it your home.
• Home (⌘⇧H), move up / down (⌘⌥↑ / ⌘⌥↓), remove (⌃X).
• Export / Import moves the list through the clipboard as JSON, handy for sharing with a colleague.

Cities you add bring their codes along as aliases, so sfo and sf work the moment San Francisco is on the list.

Menu bar

Menu Bar Clock puts the locations you choose in the menu bar, like LON 13:15 • SFO 05:15, with every location in its dropdown. Run the command once from the root search to place it, then pick locations with ⌘M in Manage Locations. The text format and separator are in Settings; the menu bar cannot colour text, so {dot} {code} {time} puts a 🟢 🟡 🔴 in front of each location instead.

Settings

Open them with ⌘, in Raycast or from the ⌘K menu in Convert Time. Changes apply the next time a command starts.

Setting	Default
Time format	24-hour
Copy template and separator	{time} {code} ({abbr}), /
Sort	west to east (or east to west, or the order in Manage Locations)
Business and shoulder hours	9–18 and 7–21
Colours for business, shoulder and off hours	Raycast's green, yellow and red for the dots; any hex colour works (the time text then stays plain), which helps if red and green look alike to you
Hour strip colours	its own green, ochre and a quiet grey for off hours; set them to match the dots if you prefer
Locations file	empty (see below)
Convert Time: default zone, return to root after copying, local row, day/month order	local, on, on, day/month
Menu Bar Clock: template, separator, icon	{code} {time}, •, on
Manage Locations: online lookup	on

Using two Macs

Raycast syncs your settings between Macs; an extension's own data stays on the Mac where it was created, and that includes the location list. To share it, point Locations file at a path inside a synced folder, for example ~/Library/Mobile Documents/com~apple~CloudDocs/Raycast/yatt.json. The extension then reads and writes that file instead of its local store. Two commands on the same Mac take turns writing it; if both Macs change the list at the same moment, the sync service keeps one version.

Questions

It says "didn't understand". One word wasn't a time, a date or a place. The header names it, and the last good result stays on screen.

cst picks Chicago, but I meant China. Add Shanghai to your locations, or type the city name. Your list always wins.

My town is missing. Add it as a custom place with a name and a zone, or turn on online lookup and search again.

I changed a setting and nothing happened. Close the command with Esc and open it again; Raycast reads settings when a command starts.
