53 week financial year – what it means for you From April 2024
There will be 53 Mondays in the 2024/25 financial year, which runs from 1 April 2024 until 1 April 2025, with the last Monday on 31 March 2025.
This happens every five or six years, because there are 365 days in a year or 366 in a leap year, which breaks down to 52 weeks in a year plus 1 day, or in a leap year 52 weeks plus 2 days. These extra days accumulate to add an extra week to the year.
52 weeks x 7 days = 364 days (one day fewer than a full year or two days fewer than a leap year).
