How many days are between Independence Day and New Year's Eve?

Q: How many days are between Independence Day and New Year's Eve?

180 days. Independence Day falls on Sunday, July 4, 2027 and New Year's Eve on Friday, December 31, 2027, which is 180 days later — 25 weeks and 5 days, or 130 business days counting Monday to Friday only. The first day is not counted and the last one is, the same way a calendar counts a stay. Both dates are fixed, so the gap is the same every year apart from leap-year shifts in the weekdays.
