1-day listings are normally used when you want to sell an item quickly and an item is time sensitive, such as concert tickets or vacation packages.
When to offer a 1-day listing
Offer a 1-day listing if you're selling time-sensitive items (for example, event tickets, package holidays or airline tickets). 1-day listings are available where PayPal is the only payment metho allowed, for auction-style formats, including listings with the Buy It Now option.
Feedback requirement for 1-day listings
To offer a 1-day listing, you must have a Feedback score of at least 10.
How soon will a 1-day listing appear on eBay?
Listings and Gallery pictures are updated throughout the day. However, if you've listed or relisted an item in the past few hours, or changed its title, your listing may not be immediately searchable when using a keyword or category search, until several hours after you've changed it. Learn more about finding an item you listed for sale.
To make your listings searchable at a specific time, you may want to schedule them a day in advance.Find out more about scheduled listings.
Changing the duration
When 2 or more hours have passed since you submitted the listing, you won't be able to change the duration of your 1-day listing.
