# Date Property Trigger

Date property trigger fires based on a specific date stored in a contact's profile, such as a birthday, created at, updated at etc. This is ideal for sending birthday emails, anniversary messages, subscription renewal reminders, or any other date-based communication.

* **Days relative** - Set how many days before or after the date the trigger should fire. Enter a number, select the time unit (Days), and choose **Before** or **After**. For example, setting it to 5 Days Before will trigger the flow 5 days before the contact's date. Set it to 0 to trigger on the exact date.

* **Select date property** *(required)* - Choose the date field from the contact's profile to base the trigger on (e.g., Contact created on or Birthday). A confirmation message will appear showing exactly when the trigger will fire based on your settings.

       Available options include: Contacts (Created at, Updated at, Subscription date, Unsubscribe date, and Birthday). 

* **Timezone** - Set the timezone for when the trigger fires. Defaults to **Recipient's Timezone** to ensure the email arrives at the right local time. You can also select a custom time zone or use your account's timezone.

* **Who should enter this automation?** - Choose which contacts are eligible to enter. You can select All Contacts, All Subscribers, or a specific segment, with an optional filter.

* **Re-trigger the flow for contacts that have been in this flow before** - Defaults to **Every time**, which is recommended for recurring date-based flows like birthdays so the automation fires each year.

Once configured, click **Select Trigger** to save.

| **Note:** This trigger is perfect for sending birthday or anniversary emails. See: [How to send birthday or anniversary emails →](https://poptin.ai/chat/PLACEHOLDER_USECASE_BIRTHDAY_URL)
