Weekend engagement often changes because people adjust their routine. Many people go out, spend time with friends, or rest away from their phones. This can reduce the time they spend looking at ads. Some audiences also behave differently based on age or work schedule. For example, students might be more active on weekdays, while workers might spend less time online during weekends. Testing different times and comparing the results can help you understand your own audience better instead of assuming one pattern fits all. What do you think?
