What time do you eat dinner?

This might not seem controversial, but what time do you guys eat dinner? This is a HUGE point of debate in my house. I live with my hubby and my mother. My mom moved in with us after my dad died in 2014, and we still regularly argue about the best dinner time. I work fairly early, 7:00 to 2:30. I personally prefer dinner earlier, like 5:30 or 6:00, because I go to bed by like 10. My mom wants to eat at like 4:30, and my hubby would prefer 8ish. We cannot come to a good consensus but have settled on earlier in the winter and later in the summer. What time do you guys eat?
