    Always synced: the tools on your board, their order and size.

  • The windows open on your start page, including what you typed in them.

  • Every note in the notepad – on the notepad page, on your board and in windows.

  • Every list of website shortcuts – on the shortcuts page, on your board and in windows.

  • Every grid in the cover grid maker – on its page, on your board and in windows.

  • Every list of bookmarked organisations in the OIN lookup – on its page, on your board and in windows.

  • Keeps your pipeline and saved recipes on all your devices. Your files are never synced – only the steps and settings.

Turning something off removes it from your account straight away. Your devices keep their own copy.

How to use the Date Difference Calculator

  1. 1 Choose a start date and an end date.
  2. 2 Choose whether the end date counts as a full day.
  3. 3 Review the calendar difference, total days and weekdays.

Calendar difference between dates

The calculator counts complete calendar months and years first, then the remaining days. It also reports total days, full weeks and weekdays.

Counting the final day

Turn on the end-date option when both endpoints should count. Weekdays are Monday through Friday; public holidays are not removed automatically.
