Every number on this page is an official published fixing, not an estimate: daily values are the Euribor fixings as published in the ECB / Eurosystem's official statistics, monthly averages are the arithmetic mean of those fixings and are cross-checked against the ECB Data Portal, and the tables are refreshed every business day after the previous day's fixing appears. Tenors use the ACT/360 convention. Where a monthly average differs from the ECB figure by more than a hundredth of a point the methodology page lists the case.
