Does Robin Work on Saturday? Debunking Stardew Valley Carpenter Shop Myths
The biggest reason a farmer might arrive on a Saturday morning to find Robin missing has nothing to do with her regular calendar. It happens because she is already working on their farm. When you contract Robin for silo and coop construction, barn projects, or farm building upgrades, she begins construction the very next morning at 6:00 AM.
During active construction jobs, Robin remains on-site on your property for two consecutive days. She stands beside the construction frame wielding her hammer, rain or shine. Because she is dedicated entirely to your build, she cannot operate her mountain cash register. If you hire her on a Friday afternoon to erect a barn, she will spend both Saturday and Sunday working at your homestead. Anyone attempting to buy wood and stone or purchase additional blueprints back at the shop during that window will find the counter unmanned.
House expansion materials require similar planning. Upgrading your initial cottage into a proper farmhouse with a kitchen takes 10,000g and 450 wood, consuming three full days of construction time. Planning those projects around festival dates or seasonal transitions prevents situations where you lock Robin out of her regular shop right when you desperately need additional crafting supplies or emergency hay silos before winter strikes.
