Date and time formatting in placeholders

There are many placeholders that contain date and time information. Slide Presenter offers a very flexible way to format how this date / time information is displayed: so called format templates.

Format templates are a string of text in which certain patterns are replaced with the actual values.

Common format templates

The whole list of patterns can be a little overwhelming. Take these as starting points:

• For dates with leading zeros:

  • MM/dd/yyyy becomes “04/29/2026”

  • dd.MM.yyyy becomes “23.02.2008”

• For times with leading zeros:

  • HH:mm becomes “23:59”

  • hh:mm b becomes “11:59 PM”

There are shorthand patterns that represent a whole localized date / time. This will show the date in the way the user is most used to, based on their browser locale. Beware that presentations created in Germany will then show a different date format than presentations created in the US.

• P becomes “04/29/2026” or “29.04.2026” etc.

• p becomes “11:59 PM” or “23:59” etc.

• Pp becomes something like “04/29/2026 11:59 PM”

Reference of available patterns

Here is a list of useful patterns for your format templates.

And there’s even more! Under the hood, Slide Presenter uses date-fns for date formatting. Everything mentioned in the date-fns documentation works here as well.
