Question 1

How do I convert epoch to time?

Accepted Answer

Paste the epoch value into the converter, confirm whether it is seconds or milliseconds, and choose a timezone. The result shows the matching readable time, date, ISO 8601 value, and UTC string.

Question 2

How do I convert a Unix timestamp to time?

Accepted Answer

A Unix timestamp is an epoch value. Enter the 10-digit seconds value or 13-digit millisecond value and the converter returns the calendar date and local time for the same instant.

Question 3

How do I get a date from a Unix timestamp?

Accepted Answer

Paste the timestamp into the converter at the top of this page — it auto-detects seconds vs milliseconds and shows the resulting date in UTC, ISO 8601, and any timezone you choose. In code, the one-liner is new Date(seconds * 1000) in JavaScript, datetime.fromtimestamp(seconds, tz=timezone.utc) in Python, or gmdate('c', seconds) in PHP.

Question 4

How do I convert a timestamp into a date in JavaScript?

Accepted Answer

new Date(1700000000 * 1000) returns a Date object — multiply seconds by 1000 first, then call .toISOString(), .toUTCString(), or Intl.DateTimeFormat for formatted output. Skip the multiplication if you already have milliseconds.

Question 5

How do I convert a timestamp into a date in Python?

Accepted Answer

Use datetime.fromtimestamp(seconds, tz=timezone.utc) for a timezone-aware UTC datetime. For local time omit the tz argument; for ISO output append .isoformat().

Question 6

Why does my Unix timestamp turn into a 1970 date?

Accepted Answer

A 10-digit seconds timestamp was passed to a function that expects milliseconds — usually JavaScript's new Date(). Multiply by 1000 first.

Question 7

What format does the date come out in?

Accepted Answer

This page renders ISO 8601 (the canonical machine-readable form), a friendly local display, the UTC string, the weekday, and the relative time. Copy whichever matches the format your code or workflow expects.

Question 8

How do I convert millis to a Unix timestamp?

Accepted Answer

Divide the millisecond value by 1000 and take the floor — Math.floor(ms / 1000) in JavaScript, ms // 1000 in Python, ms / 1000L in Java. To go the other way, multiply seconds by 1000. The converter at the top accepts both 10-digit and 13-digit inputs.

Question 9

How do I convert currentTimeMillis to a date?

Accepted Answer

System.currentTimeMillis() returns epoch milliseconds. Paste it directly into the converter — it auto-detects the 13-digit unit. In code: Instant.ofEpochMilli(System.currentTimeMillis()).toString() returns an ISO 8601 string.
