Most Cambodians get up very early and it is not unusual to see people out and about exercising at 5.30am if you are heading home ahem, sorry, getting up-at that time. Government offices, which are open from Monday to Saturday, theoretically begin the working day at 7.30am, break for a siesta from 11.30am to 2pm, and end the day at 5pm. However, it is a safe bet that few people will be around early in the morning or after 4pm, as their real income is earned elsewhere.

Banking hours vary slightly according to the bank, but most banks keep core hours of 8.30am to 3.30pm Monday to Friday, plus Saturday morning. Tourist attractions such as museums are normally open seven days a week and these days’ staff has had their arms twisted to stay open through lunch.

Local restaurants are generally open from about 6.30am until 9pm and international restaurants until a little later. Many bars are open all day, but some open only for the night shift, especially if they don't serve food.

Local markets operate seven days a week and usually open and close with the sun, running from 6.30am to 5.30pm. Markets shut up shop for a few days during the major holidays of Chaul Chnam (Khmer New Year), P'chum Ben (Festival of the Dead) and Chinese New Year. Shops tend to open from about 7am until 7pm, sometimes later.
