Meaning
Half past six: the minute hand points to the 6 and the hour hand rests between the 6 and the 7, so both hands hang toward the bottom of the dial.
It covers the morning rush of getting up and out, or an evening dinner reservation: “Table booked for 🕡, I’ll text when I’m parked.” It suits school mornings too, alongside ⏰ or 🎒.
