World Time & Timezone Converter (400+ Zones, No API)

Get the current time in any of 400+ IANA time zones, or convert a specific date and time from one zone to many others, with UTC offset and zone abbreviation. Uses the time-zone database built into Node.js (ICU) - no external API calls, so it always works even when other online tools are down.

What does World Time & Timezone Converter (400+ Zones, No API) do?

Current time in 400+ IANA time zones, or convert a date-time between zones - local only, no external API.

What can you use it for?

• Show the current time for team members or customers across several countries.
• Convert a meeting time from your zone to everyone else's before sending an invite.
• Feed correct local timestamps into scheduling, logging or reporting tools.
• List every supported time zone to build a picker in your own app.

Why use this Actor?

• Fast and cheap: lightweight HTTP-based Actor with no browser, so runs finish in seconds and cost very little.
• No API keys or accounts needed for the data source (see notes below).
• Clean, structured JSON that you can export as CSV, Excel, JSON or XML, or pull through the Apify API and integrations.
• Scheduling, webhooks and integrations: run it daily and send results to Google Sheets, Slack, Zapier, Make, n8n or your own API.

Input

Configure the run in the Input tab (all fields have sensible defaults).

Field	Type	Required	Default	Description
mode	string (now / convert)	no	"now"	'now' shows the current time in each zone. 'convert' translates a specific date-time from sourceZone into each zone.
zones	array of strings	no	-	IANA time zone names, e.g. Asia/Seoul, America/New_York, Europe/London, UTC. Ignored if "List all zones" is on.
listAllZones	boolean	no	false	Ignore "Zones" and return the current time for every supported IANA zone (~400 rows). Only applies to 'now' mode.
sourceZone	string	no	"UTC"	The IANA zone that "Date-time to convert" is written in.
dateTime	string	no	-	Wall-clock time in sourceZone, e.g. "2026-12-25 09:00" or "2026-12-25T09:00:00".

Example input

{
  "zones": [
    "Asia/Seoul",
    "America/New_York",
    "Europe/London",
    "UTC",

  ],
  "sourceZone": "UTC"
}

Output

Results are stored in the default dataset. Download them from the Output tab or via the API.

Example result

{
  "zone": "Asia/Seoul",
  "localTime": "2026-09-23T11:25:48+09:00",
  "utcOffset": "+09:00",
  "abbreviation": "GMT+9",
  "weekday": "Wednesday",
  "mode": "now"
}

Output fields

Field	Type	Example
zone	string	"Asia/Seoul"
localTime	string	"2026-09-23T11:25:48+09:00"
utcOffset	string	"+09:00"
abbreviation	string	"GMT+9"
weekday	string	"Wednesday"

How much does it cost?

The Actor is billed by Apify according to the pricing shown on the Pricing tab of this page. Runs are small and fast, and the Apify Free plan includes monthly platform credits so you can try it at no cost. You can set a maximum cost per run, and the Actor stops cleanly when that limit is reached.

Notes and limitations

• Uses the IANA time zone database bundled with Node.js (ICU) - no external API call, so it always works even when online converters are down.
• "abbreviation" comes straight from ICU and already reflects daylight-saving time (e.g. EST vs EDT), so there is no separate guessed DST flag. For some zones ICU has no short English abbreviation and returns a "GMT+9"-style fallback instead of letters - this is expected, not an error.
• For "convert" mode, dateTime is read as the wall-clock time in sourceZone (e.g. "2026-12-25 09:00"), not UTC.

Tips

• Start with a small test run, then scale up the input.
• Use Schedules to automate recurring runs and Webhooks or Integrations to deliver the data where you need it.
• Call the Actor from your code with the Apify API or the official JavaScript and Python clients.

FAQ

What format should dateTime be in?

"YYYY-MM-DD HH:mm" or full ISO like "2026-12-25T09:00:00". Seconds are optional.

How do I get every time zone?

Turn on "List all zones" - it ignores the Zones field and returns current time for all ~400 supported IANA zones.
