A calendar is only as useful as the questions it can answer, and "is this a working day?" is a harder question in the UK than a grid of numbers suggests. These pages cover 2026 to 2030 at three levels — a whole year at a glance, a single month in the usual grid, and one day in full detail — with bank holidays marked and weekends distinguished from the days that only look like a break.
Day pages carry the detail that scheduling actually depends on: the weekday, the ISO week number, the position of the date within the year, and whether it counts as a working day. Because bank holidays differ between England and Wales, Scotland and Northern Ireland, that last answer is given per nation rather than flattened into a single UK figure that would be wrong for somebody.
Two British calendars that do not start in January
The UK personal tax year runs from 6 April to 5 April, an inheritance from the switch to the Gregorian calendar in 1752 and the Treasury's determination not to lose eleven days of revenue in the process. The government's own financial year, meanwhile, runs from 1 April, which is why April is such a busy month for deadlines and why "year end" means different things to an accountant and a payroll clerk.
Older still are the quarter days — Lady Day on 25 March, Midsummer on 24 June, Michaelmas on 29 September and Christmas Day — the dates on which rents fell due and hiring contracts began. They have largely disappeared from ordinary life, but they still turn up in leases, in agricultural tenancies and in the vocabulary of the Scottish term days, which fall on slightly different dates again.
Five years of coverage is enough for most planning that has to be done in advance: checking which day of the week a date falls on before booking anything, counting working days to a milestone two years out, or simply confirming where the late May holiday lands in a year you have not thought about yet.
Common questions
Which years are covered?
2026 through to 2030, with a page for every year, every month and every individual day in that range.
Are bank holidays marked on the calendar?
Yes, and they are labelled by nation, so a date that is a holiday only in Scotland or only in Northern Ireland is not presented as a UK-wide day off.
Why does the UK tax year start on 6 April?
It is a leftover from the calendar reform of 1752. When eleven days were removed from September, the Treasury shifted the start of its year rather than shorten it, and the date has stayed put ever since.
Do the day pages show week numbers?
Yes, using the ISO standard, in which week one is the week containing the first Thursday of January. This is the numbering used in most British business and project planning.
How is the working-day count worked out?
Weekends are excluded, along with the bank holidays that apply to the nation you are looking at, so the count matches the calendar your office actually keeps.
