Another major factor for 9to5 is probably having a common time that businesses are open. Many businesses need to interact with a multitude of other companies during their working hours. Having the same working hours as every other company you need to interact with makes scheduling meetings&#x2F;phonecalls&#x2F;etc a lot easier, or reduces the need for scheduling and the overhead that comes with it. I&#x27;m sure there&#x27;s a good way to solve this too, but I can&#x27;t think of one off the top of my head at the moment.
