Sometimes, we are just too lazy/preoccupied to use our eyes to check the time. If you want your Windows 10 PC to tell you the time of day audibly, check out this article at makeuseof.com for the Visual Basic script that can add the feature manually with Task Scheduler. With those settings, your PC will have the default text-to-speech voice announce the time of day indefinitely and repeatedly every hour. If you're comfortable with the language, you can modify it to announce the time more frequently, or even add extra words. If you have a Mac, you already have a time announcement feature built-in, luckily.
