Unix Timestamp Converter
EVM block timestamps are Unix seconds since 1970, not human dates. This converter moves both directions between a Unix timestamp and a readable date so you can interpret block times. It runs entirely in your browser with no network call.

Seconds since the epoch
A Unix timestamp counts whole seconds since 1970-01-01 00:00:00 UTC. EVM blocks carry their time in this format in the timestamp field, and many contracts compare against block.timestamp for deadlines and vesting. Converting to a human date tells you exactly when a block was produced.
Seconds, not milliseconds
On-chain timestamps are in seconds, while many programming environments default to milliseconds. If a converted date lands around 1970, the value was probably milliseconds; divide by 1000 to get the correct EVM-style seconds.
よくある質問
Which time zone is used?
Unix time is defined in UTC. The tool shows UTC so it matches how block timestamps are recorded on-chain.
Is any data sent over the network?
No. The conversion is done locally in your browser with no API key and no server call.
