Provided by Hesapstan, this calculator uses official CBRT XML archive reference rates for the selected date.
Source and fields
The tool separates forex buying, forex selling, banknote buying and banknote selling. These are official reference rates, not live tradable market prices.
Non-publication days
Previous official day
When a weekend or holiday has no XML file, the UI shows both the requested date and the actual official source date used.
Limits
- No browser-side EVDS key is used.
- Bank spreads and exchange-office fees are excluded.
- Provider outage and missing-data states are shown explicitly.
Frequently Asked Questions
Is this a live rate?
No. It is an official historical CBRT reference value.
What is banknote rate?
It is the banknote buying or selling field published in the CBRT XML file.
Why can the source date differ?
CBRT may not publish rates on weekends or holidays, so the latest previous official date can be used.
