Convert dates between formats

Every system, country and programming language has its quirk for writing a date. Brazil uses dd/mm/yyyy, databases prefer yyyy-mm-dd, the United States flips to mm/dd/yyyy and code likes to speak in timestamps. The tool takes one date and translates it into all those formats at a single go.

It doesn't stop at the numeric formats. It also shows the date spelled out in Portuguese, in the ISO 8601 standard and as a Unix timestamp, which helps both for filling in a document and for debugging a database field. You pick the date in the browser's own calendar field and get the equivalents ready to copy.

The whole conversion happens in the browser. Anyone forever crossing between spreadsheets, systems and code will find a handy shortcut here, the kind that keeps you from mixing up the day and the month by accident.

Frequently asked questions

What time of day does the Unix timestamp refer to?

Midnight in your own machine timezone, not midnight UTC. Someone in London and someone in Sao Paulo get different numbers for the very same date, apart by exactly their offset. The full ISO 8601 line behaves differently: it ends in Z and pins the time to 00:00 UTC. Adjust for your offset if the system consuming the number expects UTC midnight.

Can I paste a timestamp, or a date written out in text, and get the other formats?

No. The input is the native browser date picker, meaning a day, month and year chosen from the calendar, and the conversion runs one way only. The layout shown inside the field follows your operating system language rather than the format you are trying to produce. To go the other way, starting from an epoch number, use the timestamp converter on the site.

Which language are the spelled-out month and weekday written in?

Portuguese, always, including on this English page. The row labelled as the English format follows the American written style, January 05, 2026, with the day padded to two digits. Note as well that the short-year format turns 2026 into 26, an ambiguity worth avoiding in contracts, spreadsheets and file names alike.
