The completed Nook's Cranny will open at 8 AM on the day after the plot marker is placed. Timmy and Tommy mention that they decided to name the store after a shop that Tom Nook ran long ago.
When can you build Nook's cranny?
Once you've collected enough of each resource, hand them in to Tommy in the Resident Services tent and construction will begin. Nook's Cranny will be built the next day, so if you fast-track this process, you should have the store by day 3.
