There are exactly 7 weeks and 6 days (or 55 days) between Halloween (October 31st) and Christmas Day (December 25th). This period, often referred to as the "holiday season," spans roughly 8 weeks. For travelers and shoppers in 2026, this timeframe is a critical window for planning. Traditionally, the first major "checkpoint" after Halloween is Thanksgiving in the United States, which falls on the fourth Thursday of November, roughly halfway through this period. Many businesses and cities begin their holiday transformations during the "8-week mark" (the first week of November), putting up lights and opening Christmas markets. Because this interval is relatively short, travel experts suggest booking mid-December flights and accommodations as early as the first week of November to avoid the steep price surges that occur as the gap between the two holidays closes.
