The rates here are the European Central Bank's euro reference rates, fixed once per working day at about 16:00 Central European Time from a snapshot taken at 14:10 and published for information; at weekends and on euro-area holidays the last rate stands. They are mid-market rates, so no bank or exchange desk will give you exactly this figure: card payments abroad typically cost 1–3 % more than the reference rate once the card scheme's rate and fees are in, and cash at an airport counter can be 5–10 % off. Use the result as the fair value to measure an offer against.
