Hi @DickB
Yes, @MplsCustomer is correct and this behaviour is caused by a routine (automation) called 'Workday' that is normally set as deactivated by default. This particular routine comes as standard and is in built along with a number of others such as, 'Good morning', 'Commuting home' and a few others that you can see if you use the Google Home app. You cannot actually delete these built in automations but you can deactivate them although they can be modified. You can only fully delete automations if they have been manually created.
Automations can be quite useful for carrying out regular tasks at certain regular times or by the initiation of a command word, but it does take a bit of time to fully get the hang of them.
