The best day for a first date is either Wednesday and Thursday. Monday and Tuesday are too early in the week, as people are recovering from the weekend. Friday to Sunday is not recommended for first dates because businesses can get crowded by families and couples enjoying the weekend.
The first date should be getting to know each other, which can be difficult during the weekend because most families and couples are off work, making it crowded and uncomfortable. First dates often do not last more than one night, so scheduling a weekend date is not recommended until more interest develops. Wednesday and Thursday give a nice mid-week break from work to go on a date. Monday and Tuesday are not recommended because many people's moods are at their lowest and some choose to spend these days doing chores and groceries.
