Countdowns, delivery estimates and age verification

Use time-based and informational components honestly and configure their limits.

Countdown timer#

Set Start date and End date in the Countdown timer section. The browser parses these values; use an unambiguous date/time including a timezone offset when appropriate. At expiry the display reaches zero; it does not end a Shopify discount, hide the campaign automatically, or restart a sale for each visitor.

Delivery estimate#

Delivery estimate adds Processing time to the minimum/maximum shipping days. The current calculation adds calendar-day seconds and adds a day after the configured cutoff. It does not consult carrier APIs, exclude weekends/holidays or calculate a location-specific shipping service. Store-rendered date/time behavior must be checked for your timezone and cutoff.

Age verification#

Add/show Age verification in the Overlay group and enable it. Set the age, explanatory text, confirmation and decline labels/messages, and optional image. This is a customer self-confirmation interface; it is not identity verification. Configure any actual business restrictions through the appropriate store process.

Test the boundaries#

  • Preview a countdown before and after expiry and from another timezone.
  • Check delivery dates immediately before/after cutoff and across weekends.
  • Test age confirmation, decline, browser persistence, keyboard navigation and competing overlays.
  • Use genuine campaign dates and actual store information.
