1. Add the element "Date & Time Formatter" to your page 2. Set the date that should be formatted
3. Insert the format string to decide how you want to display the date-time
4. Display the formatted date-time anywhere by getting element's "value"

For the complete list of accepted format inputs, see:

If you want to display a localized-format of the date-time (https://day.js.org/docs/en/display/format#localized-formats) remember to add the required locale in your Bubble app.
You can do so by adding the locale script inside the "SEO / metatags" section from you application settings.
You can get the locale script from here: https://cdnjs.com/libraries/dayjs
