The clocks go back on the last Sunday of October, at two in the morning, and the hour between one and two is lived through twice. The United Kingdom returns to Greenwich Mean Time until the following March, and the effect on the evenings is immediate: it is dark before six the following day and before five by the end of November.
Leave in October 2028 clusters around half term for families and around the clock change for everyone else, since the darker evenings make a week off feel materially different from one taken in September. There is no public holiday anywhere to bridge into, so it is annual leave taken in full.
October 2028 runs to 31 days and opens the final quarter of a year of 366 days. Two months remain, carrying the whole of the Christmas run-up and the tax year's midpoint somewhere in among it.
