Guides
Why these calculators are different
Every date here is counted in whole days on the UK calendar, from today's date in the UK, not the date where a server happens to be. Leap years follow the Calendar (New Style) Act 1750, the clock changes follow the Summer Time Order 2002, and Easter and Christmas bank holidays come from GOV.UK. Open "Show the workings" under any result to see the count.
