Understanding Historical Exchange Rates
What is a Historical Currency Converter?
A historical currency converterlooks up the exchange rate between two currencies on a specific past date and converts an amount at that rate. Unlike a live currency converter that uses today's rate, a historical currency converter lets you find out what a currency was worth on any date in the past. Our historical currency converter uses the European Central Bank (ECB) reference rates via the free Frankfurter API, covering 32 currencies from 1999-01-04 (the Euro launch date) to yesterday. ECB reference rates are published on every TARGET2 business day at approximately 16:00 CET.
How Our Historical Currency Converter Works
- 1. Select Your Currencies and Date: Choose the source and target currencies from the 32 available options. Enter the historical date you want to look up — or use one of the quick presets (1 year ago, 5 years ago, 2008 crisis, Euro launch). The date picker accepts any date from 1999-01-04 to yesterday.
- 2. Enter Your Amount: Type the amount you want to convert. The historical currency converter accepts any positive number including decimals.
- 3. View the Historical Rate and Converted Amount: Click Get Historical Rate to fetch the ECB reference rate for that date. The result shows the converted amount, the direct rate (1 FROM = X TO), and the inverse rate (1 TO = X FROM). If the selected date was a weekend or holiday, the nearest prior trading day rate is used.

Important Limitations
ECB reference rates are indicative rates — they represent the mid-market rate at a specific time of day and are not the rates at which banks or money changers transact. Actual transaction rates include a spread (markup) above the mid-market rate. For accounting and tax purposes, always verify the applicable rate with your financial institution or tax authority. Rates are not available for weekends, public holidays, or dates before 1999-01-04.
