WooCommerce Availability Scheduler

Description

This plugin allows you to schedule the availability of your woocommerce products.

You can choose the time and date range when your products are ready to be purchased. The “Add to Cart” button will automatically hide/show on the store, category, and product pages. A countdown timer is also displayed.
After allowing Schedule Availability for a product, it will still appear in your WooCommerce shop before the start date, but visitors will not be allowed to buy it. There will therefore be no “Add to Cart” button. Visitors can see a custom message.
COUNTDOWN TIMERS
The Woocommerce Product Scheduler plugin lets you show countdown clocks to let your customers see how much time they have left to buy, or until the end of their purchase.

DATE AND TIME EXPIRING
This plugin allows you to set expiry dates for products. After this date, the product will automatically be hidden and not available for purchase. You can also choose to make the product visible.
WordPress Multisite (each blog network has its own maintenance setting) is also installed.
