Unix Timestamp to Date

A raw Unix timestamp says nothing until you convert it. This tool turns a Unix seconds value into a readable UTC date so you can see when a block was mined or an event fired. It runs entirely in your browser.

Making block times readable

Every EVM block records its time as Unix seconds in the timestamp field. Converting that number to a calendar date lets you answer when a transaction was included or when an event was emitted, which is essential when reconciling on-chain activity with off-chain records.

Watch for millisecond values

On-chain timestamps are seconds. If your source gives milliseconds and the resulting date sits in 1970, divide by 1000. Getting the unit right keeps block times aligned with reality.

よくある質問

Does it show local time or UTC?

It shows UTC, matching how block timestamps are stored on-chain, so times line up with explorer data.

Is my input uploaded?

No. Conversion happens locally in the browser with no network request and no API key.
