This timestamp converter translates between Unix timestamps (seconds since epoch) and human dates — both directions, shown in UTC and your local time, with the current epoch ticking for reference.

Epoch: Seconds Since 1970-01-01 00:00:00 UTC — the Internet’s Native Clock

Every log line, cookie expiry and database row quietly speaks epoch. Converting clock-face times between zones is our Time Zone Converter. Part of our Conversion Calculators collection.

Worked Example (Verified)

  • Timestamp 1,760,000,000 (defaults) → Thursday, October 9, 2025, 08:53:20 UTC (04:53 EDT in New York) — a round-ish epoch milestone, verified against system clocks
  • The famous ones: 1,000,000,000 fell on Sep 9, 2001; 2,000,000,000 arrives May 18, 2033; the 32-bit signed ceiling 2,147,483,647 (Jan 19, 2038, 03:14:07 UTC) is the Y2K38 deadline for legacy systems
  • Milliseconds lurk: JavaScript’s Date.now() and many APIs return ms (13 digits) — divide by 1,000 before feeding seconds-based tools like this one; the digit count (10 vs 13) is the tell
  • Negative timestamps predate 1970 and work fine mathematically — historical dates in epoch are negative numbers

Timestamp Traps

  • Seconds vs milliseconds vs microseconds vs nanoseconds: same instant, four magnitudes across APIs — check the docs, count the digits.
  • Time zones don’t change the timestamp: epoch is absolute (UTC-based); zones only change its printed form.
  • Leap seconds are ignored by Unix time (POSIX smooths over them) — astronomers keep their own ledgers.
  • Date pickers interpret input in local time; the epoch output shifts with the reader’s zone — stated on this page, hidden on many.

Frequently Asked Questions

How do I convert a Unix timestamp to a date?

The timestamp counts seconds since 1970-01-01 UTC; date libraries (and this converter) render it in any zone. 1,760,000,000 = October 9, 2025, 08:53:20 UTC. If your number has 13 digits it’s milliseconds — divide by 1,000 first.

What is the current Unix timestamp?

It’s ticking at the top of this tool — about 1.79 billion during late 2026 — and it rises by one per second, forever, which is the entire point. Developers read it from Date.now()/1000, `date +%s`, or time.time() depending on the stack.

What happens in 2038?

Signed 32-bit timestamps overflow at 2,147,483,647 (Jan 19, 2038) and wrap negative — the Y2K38 problem for embedded and legacy systems storing time in 32 bits. 64-bit systems are immune for ~292 billion years; the remediation is an audit, not a panic.

Why do timestamps ignore time zones?

By design: an epoch value names one absolute instant worldwide. Time zones and DST are presentation-layer rules applied when humans read the value — which is why the same timestamp prints different wall-clock times in New York and Tokyo, correctly.

How do I get a timestamp for a specific date?

Use the date field here (interpreted in your local zone) or compute days-from-epoch × 86,400 + seconds-into-day (UTC). Spreadsheets and databases each have their idiom (UNIX_TIMESTAMP, EXTRACT(EPOCH…), = (date − DATE(1970,1,1)) × 86400).

Is this timestamp converter free?

Yes — free, instant, no sign-up.
