Unable to enter any houses, all doors are locked.

Hi! It's Wednesday 24th of Spring year 1 at 12:30 pm. I can't enter any establishments. I tried the Museum, The Blacksmith and Joja Mart. I can see the NPC's walking in and out of these houses but when I try to enter I'm told "It's locked..."

I was going to crack open 9 geodes today since I had the best possible luck. :( Sad.

First off, are you using any mod that changes the flow of time?
If you are try launching the game without the mods, and verifying the game integrity.

Instructions:
Go to Stardew Valley in your Steam Library, and right click on it. Go down to "Properties", and click on that. Then on the new window it brings up, go to the 3rd tab called "Local Files". Click "Verify Integrity of Game Cache".

Try that first.

Necro post, but in case others also encounter this, it's because its the Flower Dance in the forest on this day, so most of the NPCs aren't at their usual places.
