Relating to a regular day that is not a holiday or special occasion.
The ferial days of the week are often busy for most people.
Ferial comes from the Latin word 'ferialis' (meaning of or pertaining to holidays or feast days), derived from 'feria' (meaning holiday or feast). The word 'ferial' refers to something related to holidays or non-working days.
Think of 'feria' meaning holiday — that's why 'ferial' relates to things associated with holidays.
