You can specify a release date with the Musician Plus or Ultimate plan.
If you've set a future release date, your music will appear in services on the date you specified.
Here's a quick video on how to setup a custom release date for your release:
If you've set a past release date, your music will appear in services as soon as possible.
Note: If it's important that your music go live on a specific date (in all chosen services at the same time), choose a release date at least four weeks in the future. If you choose a release date less than four weeks in advance, there's a chance your album could still be stuck in a services' review queue (or some other unforeseen delay) when your release date comes around.
