How to use this tool
What is Unix Epoch Time?
Unix time (also known as Epoch time) is a system for describing a point in time, defined as the number of seconds (or milliseconds) that have elapsed since January 1, 1970 (UTC), minus leap seconds.
How to Convert Dates
Input dates or timestamps to perform instant time representations.
Epoch to Date
Enter a numerical Unix timestamp in seconds or milliseconds to reveal its date representation.
Date to Epoch
Use the datetime picker to select a date and see its equivalent Epoch integer value instantly.
Compare Zones
Review the formatted outputs in UTC/GMT, local time zone offset, and relative human descriptions.
Frequently Asked Questions
Standard time conversions definitions.
How do I identify seconds vs. milliseconds in Epoch?
Timestamps in seconds contain 10 digits (e.g. 1718300000), while timestamps in milliseconds contain 13 digits (e.g. 1718300000000). This converter automatically detects and handles both formats.
What is the Year 2038 problem?
On January 19, 2038, systems using 32-bit signed integers to store Unix time will overflow because the counter reaches its max positive value. Modern systems use 64-bit integers to represent Epoch, avoiding this crash.
