A 9am New York post lands mid-afternoon in London
9:00 AM in New York (America/New_York) converts to roughly 2:00 PM in London and 11:00 PM the same day in Tokyo, all shown in one table without manual offset math.
Time zone converter for posting
Enter one post time in your own time zone and this converter shows the same moment in 15 audience time zones, from Honolulu to Auckland, and flags any zone already on a different day. It uses the IANA time-zone database, so daylight-saving changes are applied for the exact date you pick, in both hemispheres.

Which time zones does the planner show?
Fifteen zones that cover the largest social audiences, from Honolulu to Auckland. Six of them change their clocks during the year, on different dates, so the gap between, say, New York and London is four hours for a few weeks each spring and autumn instead of the usual five. The planner works from the date you enter, so those weeks come out right.
| Zone | January | July | Clocks change in 2026 |
|---|---|---|---|
| Auckland | UTC+13 | UTC+12 | 5 April and 27 September |
| Sydney | UTC+11 | UTC+10 | 5 April and 4 October |
| Tokyo | UTC+9 | UTC+9 | None |
| Shanghai / Singapore | UTC+8 | UTC+8 | None |
| Mumbai / Delhi | UTC+5:30 | UTC+5:30 | None |
| Dubai | UTC+4 | UTC+4 | None |
| Moscow | UTC+3 | UTC+3 | None |
| Paris / Berlin | UTC+1 | UTC+2 | 29 March and 25 October |
| London | UTC+0 | UTC+1 | 29 March and 25 October |
| São Paulo | UTC−3 | UTC−3 | None |
| New York | UTC−5 | UTC−4 | 8 March and 1 November |
| Chicago | UTC−6 | UTC−5 | 8 March and 1 November |
| Denver | UTC−7 | UTC−6 | 8 March and 1 November |

How do you use the multi-time-zone posting planner?
- Choose your source time zone. Select the time zone your posting time is written in — typically your own or your team’s.
- Enter a date and time. Pick the date and time you are considering for the post.
- Read the converted table. The table shows that exact moment’s local time and UTC offset in every listed audience time zone.
- Watch for the different-day flag. A zone far enough away may already be on the next (or previous) calendar day — the table flags this explicitly.
- Pick a time that lands well everywhere that matters. Compare the converted times against your audience’s active hours in each zone before finalizing a schedule.
What does it look like in practice?
A DST-sensitive conversion
The same 9:00 AM New York post converts to a different UTC offset in January (UTC-5) than in July (UTC-4), and the planner applies the correct one automatically for the date entered.
How do you pick one post time for several time zones?
Start from where most of your audience is, then check what that moment means everywhere else. A 9:00 post in New York reaches London after lunch but lands in Tokyo late at night and in Auckland the next morning:
| Zone | Local time |
|---|---|
| Los Angeles | Tuesday 06:00 |
| New York | Tuesday 09:00 |
| London | Tuesday 14:00 |
| Tokyo | Tuesday 23:00 |
| Auckland | Wednesday 03:00 (next day) |
If two audiences are far apart, post twice rather than at a time that suits neither. For when each audience is most active, see the best time to post and the best time by country, then lay the week out with the weekly planner.
How does SkedCast handle time zones?
Each client in SkedCast can have its own time zone, and otherwise uses the workspace’s. A post publishes at the time you set on that client’s clock, and the composer shows what that is in your own time, so an agency in London scheduling for a client in Sydney sees both. Daylight-saving changes are applied for the date of each post.
Time zone converter for posting FAQ
- Does this tool account for daylight saving time?
- Yes, every conversion is computed from the actual date entered using the browser’s IANA time-zone database, so the correct seasonal offset applies automatically rather than a fixed year-round number.
- How many time zones are shown?
- Fifteen major zones, from Auckland (UTC+13 in its summer, UTC+12 in winter) to Honolulu (UTC-10), including London, New York, Los Angeles, Tokyo, Sydney, Dubai and Mumbai.
- What does the "different day" flag mean?
- It means that zone’s local calendar date is not the same as your source zone’s date at that moment — a late-evening post in one zone can already be the next morning somewhere else.
- Is this the same as SkedCast’s real posting schedule?
- No, this is a free, standalone conversion tool; it does not read or write your SkedCast schedule. In SkedCast each client can have its own time zone (otherwise the workspace’s), posts publish on that clock, and the composer shows the time in your own zone too.
- What happens during the one hour that repeats or is skipped at a DST change?
- That single hour twice a year is genuinely ambiguous or does not exist in the local clock; the tool resolves it to a valid instant rather than crashing, the same limitation every time-zone library documents.
- When do US clocks change in 2026?
- Daylight saving time began at 2:00 a.m. on Sunday 8 March 2026 and ends at 2:00 a.m. on Sunday 1 November 2026; the UK and EU change on 29 March and 25 October, so for a few weeks the gap is one hour shorter.
- Does the tool store the times I enter?
- No, the conversion happens entirely in your browser; nothing you enter is uploaded, saved, or sent to a server.
