Timestamp Converter – Turn Unix Time Into Readable Dates (and Back) Instantly

Dates and times can get messy—time zones, DST, milliseconds vs. seconds—it’s a lot. With Toolsina’s Timestamp Converter, you don’t need to memorize anything. Paste a timestamp to see the real date, or type a date to get the exact Unix timestamp. It’s fast, accurate, and super easy.

What’s a Unix Timestamp (a.k.a. Epoch Time)?

A Unix timestamp is just a number that counts how many seconds (or milliseconds) have passed since Jan 1, 1970 (UTC).
You’ll usually see it in these flavors:

Seconds: 10 digits (e.g., 1723728000)

Milliseconds: 13 digits (e.g., 1723728000000)

Micro/Nanoseconds: longer numbers used in some systems

Why it matters: timestamps are perfect for computers, but not for humans. This tool bridges that gap.

Why Use Toolsina’s Timestamp Converter?

Instant Results – Convert timestamp → date and date → timestamp in one click.

Time Zone Aware – View results in UTC and your local time (or choose any time zone).

DST-Safe – Clear handling around Daylight Saving Time switches.

Flexible Formats – Output in ISO 8601, RFC 3339, and custom patterns.

Free & Browser-Based – No installs, no sign-ups.

How It Works

Paste a Unix timestamp (seconds or milliseconds), or enter a date/time.

Pick a time zone (UTC, local, or a specific region).

Click Convert.

Copy your result in the format you need.

That’s it—no spreadsheets, no guesswork.

Key Features

Convert seconds ↔ milliseconds in one tap.

Show UTC and Local Time side by side.

Output presets: ISO 8601, RFC 3339, human-readable.

Custom format tokens (e.g., YYYY-MM-DD HH:mm:ss).

Handle leap years, DST transitions, and invalid inputs gracefully.

Common Use Cases

Developers – Debug API responses and log times.

Analysts – Convert exported timestamps into readable dates.

SEO/Content Teams – Timestamped feeds and sitemaps.

Product Managers – Sanity-check event times across regions.

Pro Tips & Gotchas (Humanized)

10 digits? That’s seconds. 13 digits? Milliseconds. If your date looks way off (like year 51325), you probably mixed them up.

DST days can “skip” or “repeat” an hour. If a time doesn’t exist locally, try converting in UTC first.

Working with very old or very far future dates? Watch out for the Year 2038 issue on some 32‑bit systems.

FAQs

1) What’s the difference between UTC and Local Time?
UTC is the global baseline. Local Time applies your region’s offset and DST rules.

2) My timestamp shows the wrong date—why?
You likely treated milliseconds as seconds (or vice versa). Divide or multiply by 1000 and try again.

3) Can I convert custom date formats?
Yes—paste your date and select a custom input pattern if needed, then choose your desired output format.

4) Does the tool support ISO 8601/RFC 3339?
Absolutely. You can both parse and export in those formats.

5) Is my data saved?
No—everything runs in your browser. Nothing is stored.

Final Thoughts

Time is complicated—your tools shouldn’t be. Toolsina’s Timestamp Converter makes it effortless to move between machine-friendly timestamps and human-friendly dates—accurately, globally, and in seconds.
