About Timezone List
Timezone List is a fixed reference page rather than a converter. It prints fifteen IANA timezone identifiers, one per line, and the list is exactly the same every time - the text panel above it is ignored, and pressing the convert button returns the same fifteen lines whatever was typed or whether anything was typed at all.
The entries begin with UTC and then run through fourteen named zones: America/New_York, America/Los_Angeles, America/Chicago, Europe/London, Europe/Paris, Europe/Berlin, Europe/Moscow, Asia/Shanghai, Asia/Tokyo, Asia/Dubai, Asia/Kolkata, Asia/Singapore, Australia/Sydney and Pacific/Auckland. They appear in the order they are written in the page rather than sorted alphabetically or by offset, so the list is not a quick way to find a zone by name - it is a short reference you read from top to bottom.
What it does not do is the more important point. Nothing is computed: no current time, no offset from UTC, no daylight-saving flag and no date is shown for any zone, so a question such as what time it is in Kolkata right now has to be answered with a clock tool instead. The list is a plain set of canonical identifiers, which is exactly what configuration files, scheduling libraries and timezone pickers want to be handed - a name such as Asia/Kolkata or Australia/Sydney is what those systems accept, in preference to an abbreviation like IST or EST that is ambiguous across regions.
The coverage is deliberately narrow. Fifteen entries cannot represent the world, and whole regions are absent - Africa has no representative, South America has none, and most of the several hundred identifiers IANA maintains are missing. There is no search box, no filter by region, no way to add a zone and no accompanying note on which cities each identifier covers, so for anything beyond a quick paste you will want the full IANA database.
How to use Timezone List
- 1 Read the list of fifteen identifiers, one per line.
- 2 Copy the identifier you need, such as Asia/Kolkata or Europe/Berlin.
- 3 Paste it into a configuration file, a scheduling job or a timezone picker.
- 4 For a zone that is not listed, look it up in the full IANA database instead.
Frequently asked questions
Does the text box above the button do anything?
No. The page shows a convert button and an input panel, but the result is a constant list held in the source, so the output is identical whether the box is empty or full. Treat it as a reference page that happens to share the layout of the other tools.
Does it show the current time or the offset from UTC?
Neither. No time, no offset and no daylight-saving state is calculated for any of the zones - it is only the list of identifiers. Use a clock or converter tool if you need the present time in a particular zone.
Why is my city not in the list?
The list is closed at fifteen entries and covers a sample rather than the whole world. Africa and South America, among others, have no entry at all. The full set of identifiers is maintained by IANA and numbers several hundred, so use that for anything exhaustive.
Are the zones in a particular order?
They appear in the fixed order written in the page, with UTC first and then the named zones grouped roughly by region. They are not sorted alphabetically and not ordered by offset, so scanning for a name is a matter of reading down the list.

How Timezone List behaves in detail
These are the specifics of this implementation — the exact ranges, defaults and fixed settings you are working with.
| Parameter | Value |
|---|---|
| Input | a text panel that the page ignores completely - the tool shows a convert button rather than recalculating as you type, and no sample text is offered |
| Output | a fixed list of fifteen IANA timezone identifiers, always the same whatever is typed |
| Coverage | UTC plus fourteen zones across the Americas, Europe, Asia, Australia and the Pacific |
| Zones | America/New_York, America/Los_Angeles, America/Chicago, Europe/London, Europe/Paris, Europe/Berlin, Europe/Moscow, Asia/Shanghai, Asia/Tokyo, Asia/Dubai, Asia/Kolkata, Asia/Singapore, Australia/Sydney and Pacific/Auckland |
| Determinism | the list is a constant string in the source, so two runs always agree and the input has no effect at all |
| Ordering | the zones appear in the fixed order written in the source, not alphabetically and not by UTC offset |

What Timezone List does not do
Knowing the edges of a tool saves more time than another list of its features. These are the cases where it will not do what you might expect.
- Nothing is computed. The page never shows the current time, an offset from UTC or a daylight-saving flag for any zone - it is a plain reference list, so a question such as the present offset of Kolkata has to be answered elsewhere.
- The list is closed at fifteen entries. There is no search box, no filter by region and no way to add a zone, and most IANA identifiers are absent - Africa and South America have no representative at all.
- Identifiers only, with no explanation. The entries are raw zone names in IANA spelling such as Asia/Kolkata and Australia/Sydney, with no local names, no abbreviations like CET or EST, and no notes on which cities each zone covers.
