What Is a Unix Timestamp?
A Unix timestamp (also called epoch time or POSIX time) represents a specific point in time as the number of seconds that have elapsed since January 1, 1970, at 00:00:00 UTC — known as the Unix epoch. This format gives every computer system worldwide a single, timezone-independent number to represent the exact same moment, which is why it’s used everywhere in programming, databases, server logs, and APIs.
Timestamp Converter to Date
Converting a timestamp to a date is the most common use case: paste a Unix timestamp (in seconds or milliseconds) into the tool above, and it instantly returns the equivalent date in three formats — UTC, your local timezone, and ISO 8601 datetime — so you always have the exact format your project needs, ready to copy.
Timestamp Converter to UTC
Since a Unix timestamp is timezone-independent by design, converting it to UTC gives you a universal reference point that reads the same no matter where in the world you or your team are located. This is especially useful when comparing server logs, debugging APIs, or coordinating events across multiple timezones — UTC removes the ambiguity that local time introduces.
Timestamp Converter to Datetime
Many databases and programming languages (like MySQL’s DATETIME, JavaScript’s Date object, or Python’s datetime) expect a formatted date-time string rather than a raw timestamp integer. Our tool automatically outputs an ISO 8601 datetime string alongside the UTC and local time, so you can paste the exact format your code or database expects without manual reformatting.
How to Convert a Date to a Timestamp
Going the other direction is just as simple — switch to the “Date → Timestamp” tab, select your date and time, and the tool instantly returns the equivalent Unix timestamp in both seconds and milliseconds:
- Select your date and time using the date picker
- Click “Convert to Timestamp”
- Copy the result in seconds (10-digit, standard Unix format) or milliseconds (13-digit, common in JavaScript)
Seconds vs. Milliseconds — Why It Matters
Standard Unix time is measured in seconds, producing a 10-digit number for current dates. However, JavaScript’s Date.now() and many web APIs use milliseconds instead, producing a 13-digit number. Our converter automatically detects which format you’ve entered based on digit length, so you don’t need to manually divide or multiply by 1,000 before converting.
Where to Find a Free Timestamp Converter Website
You’re already on one — Vexlix’s timestamp converter runs entirely in your browser, meaning your data is never sent to or stored on a server. It works for debugging server logs, working with database queries like MySQL or PostgreSQL timestamps, building API integrations, or simply checking what a specific epoch value means in plain, readable terms.
Frequently Asked Questions
How do I convert a timestamp to a date?
Paste your Unix timestamp into the converter above and click “Convert to Date.” You’ll instantly get the equivalent date in UTC, your local timezone, and ISO 8601 datetime format.
How do I convert a timestamp to UTC specifically?
The UTC result is shown automatically alongside your local time whenever you convert a timestamp — no separate steps needed, since UTC is timezone-independent by definition.
What’s the difference between seconds and milliseconds in a timestamp?
Standard Unix time is in seconds (10 digits for current dates). Many JavaScript-based systems use milliseconds instead (13 digits). This tool automatically detects which one you’ve entered.
Can I convert a date back into a Unix timestamp?
Yes — switch to the “Date → Timestamp” tab, pick your date and time, and get the equivalent timestamp instantly in both seconds and milliseconds.
Is this timestamp converter free to use?
Yes, Vexlix’s timestamp converter is completely free, runs entirely in your browser, and requires no signup
