The Day-ahead (DAM) and Itraday market (IDM)
During the transition from summer to standard time, the template for orders for 28 October is different. Market participants can place orders for 25 individual hours. With CET/CEST time zone settings, the hour from 02-03 is called Hour 3a. The additional hour from 02-03 has been added to the matrix and is called Hour 3b, as shown below. The same numbering is used for the Intraday market.
