Ten in the morning is the retail opening. Most large shopping centres unlock at ten, and since so much of daily life here happens inside them — the supermarket, the clinic, the phone shop, the tailor — that single time governs a large share of the day's errands.
It is also the usual hotel checkout window, and the point at which delivery slots for furniture, appliances and large grocery consignments begin. Counting towards ten is very often counting towards being packed, being out, or being at home to receive something.
In the cooler half of the year it is the last comfortable hour for anything outdoors with small children before the sun becomes the deciding factor; in summer that window closed three hours ago and will not reopen until after dark. The count resets daily and always points at the next ten o'clock in the morning rather than at a particular date.
Common questions
What time do the malls open?
Most large shopping centres open at ten, holding their restaurants and cinemas open much later into the night.
