Quick answer
144 business days remain between 5 June 2026 and Christmas Day (25 December 2026). This counts Monday to Friday only, excluding the Summer Bank Holiday (31 August), Christmas Day, and Boxing Day bank holidays.
If you're counting calendar days instead, there are 204 days — that includes all weekends and bank holidays in between.
Month-by-month breakdown
| Month | Working days | Calendar days | Days skipped |

| August | 20 | 31 | 11 (5 weekends + 1 holiday) |
| September | 22 | 30 | 8 (4 weekends + 0 holidays) |

| November | 21 | 30 | 9 (4 weekends + 0 holidays) |
| December (to 25th) | 18 | 25 | 7 (3 weekends + 0 holidays) |
| Total | 144 | 204 | 60 |
Bank holidays counted
These UK bank holidays fall between 5 June and 25 December 2026 and are excluded from the working day count:
- 31 August 2026 — Summer Bank Holiday
Christmas Day (25 Dec) and Boxing Day (28 Dec) fall on or after the target date, so they don't affect the count to 25 December.
Why it matters
If you're planning a project deadline, delivery estimate, or work schedule before Christmas, knowing the number of working days — not calendar days — is essential. A 144-day project started on 5 June gives a very different timeline than one measured in calendar days:
- 144 calendar days from 5 June = 27 October 2026
- 144 working days from 5 June = 25 December 2026
That's nearly two months difference — enough to miss a Christmas deadline if you miscount.
