Convert a Timestamp to a Date

The timestamp is a number of seconds counted from a date called the Epoch (POSIX time), corresponding to January 1, 1970 at 00:00:00. It was created so that measuring time and performing related calculations would be easier for computers.

Understanding how the timestamp works

The timestamp represents the seconds elapsed since the so-called epoch date. The seconds can be positive for dates after January 1, 1970 at 00:00:00, or negative. In the latter case, they represent dates before the Epoch (POSIX time).

Calculate the timestamp or the human-readable date

The value of the timestamp converter lies in the fact that a number of seconds is not usable by a human. To make things clear, this calculator converts it into a readable date.

Using the converter

This converter is very easy to use. Just enter a date in the MM/DD/YYYY HH:MM:SS format to get the corresponding timestamp. Conversely, by typing a timestamp in the dedicated field, the date is displayed automatically.

By pressing the Today button, you get the timestamp of the current date and time.

Save and export to CSV

The CSV format is a file type compatible with modern spreadsheets such as Excel or OpenOffice. By clicking the Save button, the data is recorded in a table, ready to be exported as CSV. This table can also be converted to PDF, then opened with a PDF reader.
