Question: how many working days in a year for a 4 day week?
Answer: And here's how you do it. Leave allowance is calculated simply by multiplying the number of days worked a week by 5.6. A five-day week entitles 28 days' annual leave a year. So, someone working a four-day week would be entitled to: 4 days x 5.6 weeks = 22.4 days.
