The time "20:00" refers to 8:00 PM in a 24-hour clock format. This system is commonly used in military, aviation, and many countries around the world to avoid confusion between AM and PM times. At 20:00, many people are finishing their workday or preparing for evening activities. In some cultures, this is a typical time for dinner or social gatherings, while in others, it may signal the start of nighttime entertainment, such as movies or events.
