How to convert Unix timestamps in Obsidian
Confirm whether your source uses seconds or milliseconds before converting the number. As of October 2026, Obsidian can hold the source and readable result together in a Markdown note. Epoch Note Converter previews both units and lets you apply a chosen value.
Background
The number 1000 can describe one second after the epoch or sixteen minutes and forty seconds after it. A valid date can't prove which unit your source used.
2 ways to do it
Convert explicitly with JavaScript
In a browser console,
new Date(1000).toISOString()returns the UTC value for 1000 milliseconds. Multiply a seconds value by 1000 before passing it to Date.- limits
- You must confirm the unit and copy the result into your note yourself.
Epoch Note Converter from this site
Select the integer and open the conversion preview. Choose a labeled unit and zone, then insert beside the original or replace the selection.

- Signed integers are supported, but fractions and exponent notation are not. A changed source note requires a fresh preview.

Choose the unit used by your source and a UTC or local result.
Select Insert beside original or Replace selection.
Common questions
Which zone should I record for a shared timeline?
UTC provides an explicit result ending in Z. If you choose a local result, retain its numeric offset for later interpretation.
Can one column contain mixed timestamp units?
A Pro column choice applies one unit to its rows. Use separate selections when the source mixes seconds and milliseconds.
