 many of the churches that were starting in the early days of Christianity, they worshipped all kinds of different times, sometimes on Wednesdays, sometimes on Saturdays, sometimes on Sundays. The important thing is that you do not forsake the gathering of the brethren, that there's time to gather together in the church, that you do have downtime, otherwise you'll implode. You can only work so much, you can only do so much, and you need time to recuperate.
