Lunchtime is when we eat a midday meal. It's usually after morning work or school and before afternoon.
So, lunchtime is a common time for people to take a break from their daily activities and grab something to eat. Many workplaces have a designated hour for lunch, and people often plan their schedules around it. Students typically go back to class after eating their lunch, while office workers might use the time to catch up on emails or chat with colleagues. Some people also like to do errands or run personal tasks during lunchtime, but usually just before they head out, most people want something quick and easy to eat - maybe a sandwich, salad, or leftovers from last night's dinner.
The time or hour at or around which lunch is normally eaten.
