There are 92 days between 1 July 2027 and 30 September 2027 — 66 weekdays, 26 weekend days and 65 business days (weekdays minus US federal holidays). The range covers 3 months, from Thursday, 1 July 2027 (Thursday) to Thursday, 30 September 2027 (Thursday). This page gives the exact count, the month-by-month breakdown, and how the count is worked out.

The count

Count Value
Total days (1 July to 30 September 2027, inclusive) 92
Weekdays (Monday–Friday) 66
Weekend days 26
Business days (weekdays minus federal holidays) 65
Full weeks 13 (plus 1 days)

The count is inclusive: it counts both the first day (1 July) and the last day (30 September). The days between dates calculator uses the standard convention of counting the days you add to the start date to reach the end date, which for this range gives 91 days — one less than the inclusive count, because the start day itself is not counted. Both conventions are correct; they answer slightly different questions, and the difference is always exactly one day.

How the count is worked out

The range is counted month by month, because the months have different lengths. July has 31 days, August has 31 days, September has 30 days — 92 days in total. The weekdays are counted from the real calendar: each month starts on a different weekday, so the number of Saturdays and Sundays differs from month to month, and the table above shows the exact split. The business days subtract the US federal holidays that fall on weekdays in the range: Labor Day (6 September).

The range in the year

The range from 1 July to 30 September 2027 starts 181 days into the year and leaves 92 days after it ends — 365 days in the year in total, since 2027 is not a leap year. It spans the whole of quarter Q3 of 2027, and it begins in summer in the Northern Hemisphere (the seasons are reversed in the Southern Hemisphere).

The federal holidays inside the range are Independence Day (4 July 2027), Labor Day (6 September 2027). Each one that falls on a weekday costs a business day — that is why the business day count (65) is lower than the weekday count (66). If you are planning a project or a deadline across this range, the holidays are the days to check first, before you promise a date.

The same range in other years

Year Total days Weekdays Business days
2026 92 66 65
2027 92 66 65
2028 92 65 63

The range is 92 days in 2027 and the same number of days in the adjacent years, except where February is involved: a leap year adds one day to any range that includes February. This range does not include February, so the total is the same every year — only the weekday split changes.
