I was just trying to find out how many Euros a specific US invoice equaled last year at the time that I paid it.

Where can I find the exchange rate from 10 Dollars to Euros on April 1, 2007?

Sadly, just entering it into Google won't work of course, since over the last year the Dollar-to-Euro exchange rate has changed more drastically than a beer lover's facial expression after a sip of Coors Light: Searching for "10 dollars to euros" there reports 6.42 Euros at the moment.

After a little digging however, I found Bank of Canada's currency conversion page, where you can request daily conversion rates dating back until 1997.

According to that page, in our little example above, 10 US Dollars equaled 7.48 Euros at the time.

Very useful, indeed!
