Act/Act Day Count Convention for Deposit Accounts


The introduction of the Act/Act day count convention. This would mean that the actual number of days in the period divided by the number of days in the current year are used. For example:

01.02.19 to 01.03.19 = 28/365

01.01.20 to 01.02.20 = 31/366

01.02.20 to 01.03.20 = 29/366
