Hours in each month
A 31-day month has 744 hours, a 30-day month 720, and February 672, or 696 in a leap year. On UK clocks, the month with the spring clock change is an hour short and the autumn one an hour long: March 2026 had 743 hours and October 2026 has 745.
Working hours in a UK year
A full-time job of 37.5 hours a week comes to 1,950 hours over 52 weeks. Most workers on a 5-day week are entitled to at least 28 days' paid holiday a year, and the employer can count bank holidays within it (GOV.UK holiday entitlement). Take off 28 days of 7.5 hours, or 210 hours, and you get about 1,740 hours.
Using the real 2026 calendar: 261 weekdays × 7.5 hours is 1,957.5 hours. Less 28 days of leave including the 8 bank holidays, that is 233 days, or 1,747.5 hours. On a 40-hour week the same year gives 1,864 hours.
Do the clock changes make a difference?
Not to the year's total. In 2026 the UK clocks went forward on Sunday 29 March, so that day had 23 hours, and they go back on Sunday 25 October, giving a 25-hour day. The two cancel out within the year. They do matter for a single shift: anyone working through the night of 24 to 25 October 2026 works an extra hour. See the clock change dates.
