2024 is a leap year, so the span from 1 January 2024 to 1 January 2025 is 366 days. The extra day is 29 February. Leap years land on most years divisible by four, which is why 2024, 2028 and 2032 all have 366 days.
Method & sources
Day counts use the Gregorian calendar and are computed on calendar dates in UTC, so daylight-saving changes never add or remove a day. The count excludes the start date and includes the end date — the same convention as subtracting one date from another.
