It is currently Junuary 6th. On Junuary 17th, it's Croppaday!
Here are the instructions for pleasing Mab by properly celebrating Croppaday:
All day long (4 real hours), everyone in the world will go to Groddle Forest Junction and drop as many harvested crops and purchased seeds as possible directly to the left of the Subway and the street sign. There's a 4-hour window, so there's plenty of time for everyone in the world to delight the heck out of Mab.
Here is a diagram showing the intended drop-off zone:

Happy cropping!
