We have introduced into our English language the term 24/7. That is often used in conjunction with “convenience”. I work in an organisation where working 9-5 is not known. Life on-board our ship, Logos Hope, starts around 7am and finishes around 10pm. We operate across huge time zones, from Australia to America and several in between. So whilst people work an 8 hour day, it may be very different to my 8 hours. Subsequently you may find people wanting to get their work completed and need your input, when your work day has finished. You may or not be available.
I like that phrase in Isaiah 60:11 “Your gates will be open continually” This phrase is used to show both security is assured and availability is certain Rev. 21:25 25 In the daytime (for there will be no night there) its gates will never be closed; We have 24/7 access to the throne of God!
