New Year's Day is the best day to buy Bitcoin. Up 2% on average the next day over the past 13 years, with an 84.6% win rate.

Based on 13 years of Bitcoin price data from May 2013 to May 2026. For long holds it looks like the date you buy BTC on doesn't matter, but New Year's Day stands out as the date with the strongest returns.

Across the last 13 New Years, Bitcoin averaged +2.01% the next day and closed higher 11 of those 13 times, suggesting a broader holiday effect.

Similarly, US federal holidays averaged +0.77% the next day versus +0.19% on a normal day, roughly 4x, and they beat non-holidays in 11 of 14 years. The likely driver is the same January momentum you see in stocks, where fresh capital comes in at the start of the year and money rotates out of December tax-loss selling.
