Convert Unix timestamps to dates, UTC, ISO 8601, milliseconds, microseconds, and nanoseconds.
Enter epoch time in seconds (10 digits)
Select or enter a date and time
Epoch time, or Unix time, counts the seconds that have elapsed since midnight UTC on January 1, 1970. Developers use it in server logs, APIs, databases, distributed systems, and scheduling workflows because it is numeric and timezone-neutral.

An epoch time converter turns Unix timestamp seconds into a readable date and converts a selected date and time back into epoch seconds. Unix epoch time counts seconds from January 1, 1970 at 00:00:00 UTC, which makes it useful for APIs, logs, databases, analytics events, and distributed systems.
A server log, webhook payload, analytics event, or database record often gives you a number instead of a readable date. Use this epoch time converter when you need to convert timestamp to date, date to timestamp, Unix epoch to UTC, current timestamp to ISO 8601, or seconds to milliseconds without opening a spreadsheet or writing a one-off script.
The converter keeps the timestamp input, date picker, timezone search, unit outputs, and copy buttons in one compact workspace. It supports UTC and searchable city timezones using the Randomly.online city timezone JSON data. If you are coordinating local and UTC time, try the UTC to Local Time Converter, Local Time to UTC Converter, or Time Zone Converter.
Epoch time is timezone-neutral. The number 1719990999 represents one exact moment. Formatting that moment in UTC, Asia/Kolkata, America/New_York, or another IANA timezone changes the displayed clock time, but the timestamp still points to the same instant.
A 10-digit timestamp usually means seconds. A 13-digit timestamp usually means milliseconds. JavaScript Date values commonly use milliseconds, while many APIs, SQL tables, Linux commands, and event streams use seconds. This page shows seconds, milliseconds, microseconds, and nanoseconds so you can match the format expected by your code, database, or API without manual multiplication.
Enter a Unix timestamp in seconds, such as 1719990999. The conversion result instantly shows the readable date, UTC ISO 8601 value, local browser date, milliseconds, microseconds, and nanoseconds. If the number has 13 digits, treat it as milliseconds or copy the milliseconds card instead.
Open the custom date picker or type a value in YYYY-MM-DD HH:mm:ss format. Select UTC or search a city timezone, then apply the date and time to generate the matching epoch timestamp. Before copying, confirm the timezone badge because daylight saving rules can change the displayed local time for the same timestamp.
Use the unit cards for exact output. Copy seconds for Unix commands and many APIs, milliseconds for JavaScript, ISO 8601 for JSON and reports, and local human date for documentation or support tickets.
Example 1: 1719990999 seconds converts to Thursday, July 4, 2024 at 12:43:19 PM UTC. The same moment is 1719990999000 milliseconds and 1719990999000000000 nanoseconds.
Example 2: If a server log stores 1719990999000, the value is probably milliseconds. Divide by 1000 to compare it with 10-digit Unix timestamp seconds, or use this converter to copy the matching unit directly.
Example 3: If you choose Mumbai from the timezone search, the readable local time changes to Asia/Kolkata, but the epoch seconds still represent the same UTC instant.
The timezone display uses browser-supported IANA timezone names, the same naming system used by modern operating systems and many programming environments. Daylight saving time is handled by the browser based on the selected timezone and exact date.
Your timestamp, selected date, timezone search, and copied output stay inside your browser. Randomly.online does not require an account and does not upload your timestamp conversion data to a server.
Useful references for the concepts used here include MDN Web Docs for JavaScript date milliseconds, the IANA Time Zone Database, and Schema.org structured data vocabulary.
An epoch time converter changes Unix timestamp numbers into readable dates and converts selected dates back into timestamp seconds. Unix epoch time counts seconds from January 1, 1970 at 00:00:00 UTC.
Epoch seconds are usually 10 digits. Epoch milliseconds are usually 13 digits because the seconds value is multiplied by 1000. JavaScript Date values commonly use milliseconds, while many APIs and databases store seconds.
Yes. Unix timestamp values represent one UTC-based instant. Formatting that instant in a local timezone changes the displayed clock time, but it does not change the underlying timestamp.
Select a date, time, and timezone in the converter. The tool calculates the matching UTC instant and returns the Unix epoch seconds plus milliseconds, microseconds, nanoseconds, and ISO 8601 output.
The timestamp identifies the same exact moment, but local formatting changes by timezone and daylight saving rules. Check the selected city or UTC setting before copying a result into logs, reports, or API payloads.
Yes. A 13 digit timestamp is usually epoch milliseconds. Use the milliseconds output card or divide the value by 1000 to compare it with a standard 10 digit epoch seconds value.
Yes. The conversion runs in your browser. Your timestamp, date, timezone search, and copied results are not uploaded to Randomly.online and no account is required.
