How do I send a journey message a set number of days before or after a user's date?

Use a Condition split with a relative date, so each user is checked against their own date instead of one calendar date for everyone.

Date event attribute:

1. Select Event as the condition type and choose the event in Event from Journey.
2. Under Attribute, select a Date attribute. A Date frame dropdown appears next to it.
3. Choose Days ago or Days ahead instead of Specific date.
4. Pick the condition and enter day counts instead of a date:
5. Days ago offers less or eq, is, greater or eq, and between.
6. Days ahead offers only between, with two day counts (for example, 10 and 15 for "10 to 15 days ahead").

Switching Date frame resets the condition and any branches you added. Changing the attribute resets Date frame back to Specific date.

Date tag: with Tag as the condition type, the Condition dropdown for Date tags offers relative and anniversary conditions such as days ago, between N and M days ahead, and anniversary is in N days. Anniversary conditions allow up to 2 branches instead of the usual 10.

Users who don't match any branch go to All other users.
