Every number on this page is a published fixing, not an estimate: daily values come from the Bank of Finland's copy of the Euribor series, monthly averages are the arithmetic mean of those fixings and are cross-checked against the ECB Data Portal, and the tables are rebuilt each 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.
