The count
| Count | Value |
|---|---|
| Total days (1 March to 31 May 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 March) and the last day (31 May). 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. March has 31 days, April has 30 days, May has 31 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: Memorial Day (31 May).
The range in the year
The range from 1 March to 31 May 2027 starts 59 days into the year and leaves 214 days after it ends — 365 days in the year in total, since 2027 is not a leap year. It spans quarters Q1 and Q2 of 2027, and it begins in spring in the Northern Hemisphere (the seasons are reversed in the Southern Hemisphere).
The federal holidays inside the range are Memorial Day (31 May 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 | 65 | 64 |
| 2027 | 92 | 66 | 65 |
| 2028 | 92 | 66 | 65 |
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.
