How to Get Start of 10-Minute on Shortcuts

by Rian

Shortcuts on iOS and macOS are not the most documented tool to navigate, and one particular thing that catches me off-guard every time is the lack of integration for date and time. For example, when I hit session limits on Claude, I usually set a reminder for when it resets. And it resets usually at 10-minute intervals, 10:10, 10:20, and so on. Oddly enough, Shortcuts don’t have an action for this.

To clarify, there is an “Adjust Date” action, that can be set to “Get Start of Hour” and “Get Start of Minute”. While they are useful in their own right, it is not the behavior I wanted. I wanted an action that would round down to 10-minute.

1. Download the shortcut through the link.
2. The shortcut takes a date & time input and returns the “Get Start of 10-Minute” equivalent. Here’s an example:

Jun 25 2026 10:23 would return Jun 25 2026 10:20.

The logic behind the shortcut is straightforward; feel free to tinker with it. Mine formats the date into two separate variables, date without minute and a round-down integer for minute, then concatenates them again. It’s quite the niche action to be included, but I think most would find 15-minute or 30-minute intervals to be useful in their own reminder automation.
