January carries the one bank holiday observed on the same date across the whole United Kingdom without argument: New Year's Day. Scotland adds a second on 2 January, a recognition that Hogmanay has never finished tidily at one in the morning, and where either date lands on a weekend the day off moves to the next working day instead. Nothing else in January 2029 interrupts the working week anywhere in the country.
January opens the first calendar quarter of 2029 and sits in the tenth month of the tax year, which began on the previous 6 April and has until 5 April to run. Businesses closing their books at the end of January are therefore working to a monthly cycle, a quarterly one and a tax year that agrees with neither, which is why so much accounting software carries three separate calendars.
The turn from January into February closes the tax deadline that dominates the second half of the month and lets the calendar breathe. What follows is a month with no bank holiday anywhere in the United Kingdom, a week of half term somewhere in the middle of it, and the first snowdrops in sheltered ground.
