Bookings Calendar for WooCommerce

When it happens the most common issue is the user is viewing calendar in Month mode, and bookable products are divided by small blocks of days, hours or minutes. This cause heavy CPU load to calculate events availability, and the solution is to set higher Booking duration blocks, or/and limit the calendar to display only in Day or/and Week mode.
