The most popular month of the year to have a Saturday yard sale is August. The second Saturday in August is known as National Garage Sale Day when many homeowners hold summer yard sales.
However, some experts say that for states that experience winter, the best months to hold garage sales are April, May, June and September. The early spring months are ideal because people want to go outdoors after the winter's cabin fever and homeowners get ready for spring cleaning. The end of summer is also ideal for yard sales because of the cooler weather and less competition.
Experts also assert that Saturdays are the best days for yard sales and holding them earlier in the day before the midday sun comes up brings in more customers. They also advise homeowners to time their yard sale closer to the first or 15th day of the month when people receive their paychecks. Homeowners must also avoid holding yard sales on holiday weekends unless they live in resort towns that get an influx of visitors.
