Understanding Unix timestamps
A Unix timestamp is a single integer that represents a moment in time. It counts the seconds since midnight UTC on January 1, 1970 — a moment called the Unix epoch. This simple format is used across virtually every programming language, database, and operating system.
JavaScript uses milliseconds by default (Date.now() returns milliseconds), while most server-side languages and databases use seconds. This tool handles both and auto-detects based on the length of the input.
Timestamps are timezone-agnostic — the number 1713440000 means the same moment everywhere in the world. The converter shows both UTC and your local timezone interpretation.
Frequently Asked Questions
What is a Unix timestamp?
A Unix timestamp (or epoch time) is the number of seconds that have elapsed since January 1, 1970 00:00:00 UTC. It is used by most programming languages and databases to represent dates.
Does this support milliseconds?
Yes. If the timestamp has 13+ digits, it is automatically treated as milliseconds. You can also toggle between seconds and milliseconds manually.
What timezone is used?
The converter shows both UTC and your local timezone. The Unix timestamp itself is always UTC-based.
What is the Year 2038 problem?
Systems using 32-bit signed integers for timestamps will overflow on January 19, 2038. Most modern systems use 64-bit integers, avoiding this issue.
