How to Add a Countdown Timer in Shopify Impulse Theme

Unlike Shopify's free themes, Impulse ships with a native countdown timer section — no app required for a basic sale-deadline countdown.

Steps

1. In your Shopify admin, go to Online Store > Themes and click Customize on Impulse.
2. Click Add section and choose Countdown timer.
3. Set the end date and time your sale or promotion actually ends.
4. Set the heading text and what happens when the timer hits zero (hide the section, or show a "sale ended" message, depending on what Impulse offers).
5. Click Save.

Set a real end date and follow through on it — a countdown that resets or never actually ends trains shoppers to ignore your urgency messaging.
