WooCommerce lets you set a coupon 「Expiry date」 but not an exact time.
This lightweight plugin adds a 「Coupon expiry time」 field (HH:MM, 24h) to the coupon edit screen.
When both date and time are set, the coupon will expire on that date at the time you specify.
Key points
* Works alongside WooCommerce』s native coupon expiry date.
* Time is stored internally as seconds since midnight and combined with the date.
* No changes to your theme or checkout templates required.
Usage
- Set Expiry date as usual in WooCommerce.
- Set Coupon expiry time in
HH:MM(24-hour) format, for example17:30. - The coupon will be valid until the combined timestamp; after that, it will be treated as expired.
