Understanding time delays in date property flows
You will learn
When you configure a flow to start before a specific date, a target date delay component is automatically created to serve as an anchor point within the flow. This component will have a target icon and will say Wait until person's [Date Property]. When using time delays in this type of flow, they appear different depending on whether they are used before or after the anchor point. This article goes over using time delays in date-based flows.
Time delays before the target date delay
If you add a time delay before the anchor point, it becomes a countdown to the profile’s date property. In Time delay details, enter a number in Wait until, select Days, Weeks, or Months, and choose the time of day. For example, a delay set to 3 days before a birthday waits until 3 days before that profile’s birthday, rather than 3 days after the preceding step. Click Save to apply the settings.

Time delays after the target date delay
If you add a time delay after the target date delay, it waits after the preceding step, like a regular time delay. Enter the duration in Time delay details and select Days, Hours, or Minutes; then click Save. For example, a 14-day delay after a message on the target date schedules the next step 14 days after that message.
