Tag date & time
Overview
Tagging dates and times correctly in your schema ensures search engines can interpret and display time-sensitive content accurately—whether it’s for events, blogs, promotions, or announcements.
Milestone Schema Manager allows you to easily tag page elements that contain date or time values. This guide walks you through how to format and tag those values for schema properties like startDate, endDate, or datePublished.
Why Accurate Date/Time Tagging Matters
Structured data helps Google and other search engines understand when an event is happening or when a post was published. But the value must be:
- Properly formatted
- Assigned to the correct property
- Free of unrelated text or noise
This is especially important for schema types like:
- Event
- BlogPosting
- NewsArticle
- Offer
