What this date difference means
The result counts elapsed calendar days, without adding an extra day for the starting date. If you need every date on a schedule including both endpoints, the corresponding count is 365 days.
The same span is 52 complete weeks plus 0 days. The years, months and days answer uses calendar boundaries rather than assuming that every month has 30 days.
A full calendar year or a gap between two dates?
This is the first-to-last-day span of 2026. The usual date-difference result measures the days elapsed after January 1 and up to December 31. A schedule that includes both January 1 and December 31 counts one more day.
For year-long contracts, check whether the start date is counted and whether the end date is inclusive. Do not assume that elapsed days and days covered by a contract are interchangeable.
