Due Dates & Reminders

Set deadlines that surface in the right place at the right time — on the card, in your inbox, on your calendar, and in Slack if you want.

Overview

Cards can have a start date, a due date, or both. Reminders fire on a schedule you choose, with delivery to email, in-app, and any integration you've connected (Slack, calendar, webhook).

Reminder options

At due time

Fires exactly when the deadline hits — useful for meetings or hard cutoffs.

1 hour before

Last-mile heads-up. Great for tasks that take prep time.

1 day before

The most popular setting — enough time to act without too much noise.

1 week before

Strategic heads-up for big milestones, releases, or board reviews.
