what time of day do people go to gym

i normally do cardio during lunch hour at work then of an evening after put kids to bed i do wieght training

now due to it being valentines day i went during lunch to do wieght training instead of tonight so could spend time with misses

but i found it wierd and did not have motivation i do of an evening
got me thinking why this could be
could it be due to just its the routeen im stuck it so never felt right
or could it be by 8pm when go gym i have had 5 meals by then good hit of carbs and come pre workout drink
or something else
i have been thinking about swapping over and doing it other way round but now in 2 minds as want to push as hard as do normally

any thought would be nice
cheers
