Breakfast for me is usually between 7 AM and 10 AM, depending on when I get up or if I have school. My breakfasts are somewhat large, but still smaller than dinner.
Lunch is usually around noon. If I have breakfast late, it might be around 1 PM to 1:30 PM. Lunch is probably my lightest meal. I usually make lunch myself, though Mum will sometimes make it if she's home (she has a part-time job at a pizzeria, and her schedule is kind of irregular).
Dinner is usually at 6:30 PM, occasionally later. My family usually has rather large dinners. Mum cooks most of it, though Dad helps out too sometimes. If we're at my grandparents' house, dinner might be at 7:30 PM since they're more traditional.
I'll have a snack between 8 PM and 9 PM, and sometimes another one between 3 to 3:30 PM.
