Hey @Svetlana
The days that are counted as absences are all based on the validity settings within your absence type. According to your current set up, I would assume that you have it set up according to the employee’s work schedule which does not include weekend work. However, I would need more details on this.
I would highly suggest reading through our helpcenter guide on Define the Range of Absence Types (Valid On) as this will give you a better idea of this setting. For example, if you want for every day of the week to be counted as an absence, you would choose the Mon-Sun option.
Please let me know if you require more information after reading through this.
Best regards,
Conor
