How does my phone know that “tomorrow” is technically “today”?

4 Upvotes

Hey all, I’ve been discovering a weird phenomenon over the past few nights, and was wondering if someone could explain *technically* how it works. Not sure if anyone else has brought this up before.

Late at night, before I go to bed, I’ll usually ask Siri to set some reminders for the next day/morning. However, it’s after midnight in which this happens. Take a Sunday night for example. I’ll say, “Hey Siri, set a reminder for tomorrow at 9am to do the dishes”, and even though it’s say 12:30am or 1am (so really Monday morning) it will still set the reminder for that Monday at 9am. Not Tuesday at 9am, which is not what I want but technically correct. Hope this makes sense.

I’ve yet to figure out when the threshold is of when “tomorrow” actually becomes the next day, or if your phone just knows you haven’t gone to bed yet and assumes “tomorrow” always means the day after your most recent sleep period. Has anyone experienced this, or can someone explain it to me?
