The rates come with the page, so this works on a plane or in a market with no bars, and your browser never asks anyone for them. If we haven't got a rate, you get a dash — never an invented number.

One habit worth more than this tool: when a card machine or ATM offers to charge you in pounds, always decline and pay in the local currency. That "service" costs 3–6%.

Rates from the European Central Bank, with the pound figures calculated by us from their euro reference rates. Dirham, dong, riel and kip come from HMRC's monthly customs rates, which are set once a month, and contain public sector information licensed under the Open Government Licence v3.0. Both are for information, not for transactions.

Shifting your body clock an hour a day before you fly is the difference between losing a day and losing a week. Tell it where you're going and how long you've got.

The rule people get wrong: 90 days in the Schengen area isn't 90 days then a reset. For every day you're inside, you count back 180 days and add up everything in that window. Add your trips and this finds the tightest day for you.

Add this trip

Counts arrival and departure days as full days inside, which is how the Schengen rule is written. Your trips are kept on this device so they are still here next time, which is the whole point of a counter you come back to. Nothing is sent anywhere, and you can see and delete them on the storage page. This is arithmetic, not immigration advice: check the official rules for your nationality before you book.
