Per Spotify's Service Level Guidelines, in order to make sure your album and tracks go live on their street dates, Spotify informs us that we must deliver your content at least 5 business days before the album's street date*. Since Catapult has it's own Quality Control processes in place that can take anywhere from 1-4 days, we recommend you consider these lead times before setting your street date.
Content can definitely go live sooner than 5 business days in Spotify (We often see content go live within 48 hours), however there is no assurance that this will happen per Spotify's Service Level Guidelines).
*Metadata updates also require a lead time of 5 business days to ensure the changes take effect.
