The prices for Saturdays and Sundays (weekends) are both included, even if they are the same.

The day-ahead price is applicable to the next working day after publication; a day-ahead price published on a Friday is applicable to the following Monday unless that Monday is a holiday. The weekend price is applicable to the consecutive non-working days after publication, namely the weekend days and, if applicable, holidays adjacent to a weekend. In other cases, such as a holiday in the middle of the week or other days when no price is published, we apply the same price as the previous calendar day. TTF DA is expressed in EUR/MWh.

These prices are published by ICIS in the ESGM report (Heren European Spot Gas Markets) under the title "TTF price assessment". ICIS Website: www.icis.com/energy.
