Working days are the weekdays: Monday to Friday, excluding Saturday and Sunday. Public holidays are not subtracted here — a public holiday that falls on a weekday is still a working day by this definition, unless your employer treats it as a day off. If you need the count excluding holidays, that is the business day count: see business days in may 2028, which is 22.

How the count is worked out

Step one: count the days in the month — 31 for May 2028. Step two: count the weekends. May 2028 starts on a Monday, so the Saturdays and Sundays fall on the dates shown in the table — 8 weekend days in total, leaving 23 weekdays. Step three: there is none — working days are the weekdays, so the answer is 23. The days between dates calculator does the same calculation for any date range, and the date calculator works out what date it is a number of days from now.

May in other years in other years

The same month in the adjacent years, for comparison — the number changes because the calendar shifts by one day each year (two after a leap year), so the same month starts on a different weekday.

May 2028 in the year

May is the 5th month of 2028 — the 2nd quarter of the year (Q2). There are 121 days in the year before May begins, and 214 days left in the year after it ends. In the Northern Hemisphere it is spring; in the Southern Hemisphere the seasons are reversed. 2028 is a leap year, with 366 days.

The federal holidays still to come after May 2028 are Juneteenth (19 June 2028), Independence Day (4 July 2028), Labor Day (4 September 2028), Columbus Day (9 October 2028), Veterans Day (11 November 2028), Thanksgiving Day (23 November 2028), Christmas Day (25 December 2028). If you are planning the rest of the year, those are the days to watch: each one that falls on a weekday costs a business day, and each one that falls near a weekend tends to become a long weekend. The days between dates calculator counts the days to any of them, and the holiday countdowns show the countdown to each one live.

Planning with May 2028

22 business days is 4 working weeks and 2 days. If you are planning a project, a deadline or a holiday, that is the capacity of the month: 22 days on which offices, banks and government departments are open. The weekends — 8 days — are the days off, and the federal holidays are the days to check before you promise a delivery date. For the same month last year, see working days in may 2027.
