Final answer:
The best month for Daniel to have his garage sale is July, as it is just before the major U.S. holiday of Independence Day and usually has good weather, which attracts more garage sale traffic.
Step-by-step explanation:
The most favorable month for Daniel to have a garage sale, based on research trends suggesting that such sales do well before major U.S. holidays, would be July. July precedes a major holiday, Independence Day, when people are often in good spirits, have time off work, and may be looking for bargains. Additionally, the weather in July is generally warmer, which is conducive to outdoor activities like garage sales. On the other hand, January is after the holiday season when people may be out of funds, while November is busy with Thanksgiving preparations. April might have unpredictable weather and is not as close to a major holiday as July.
