I have a busy work schedule, but I randomly got Saturday off and I never get It off so I thought about asking her out on a date. But it's her birthday but she doesn't know I know it's her birthday (Facebook) should I still take the risk and ask her out? Even though her birthday is an excuse not to?
If you don't already know her then asking her out on her birthday is a little risky. She might want to spend that day with her friends or family, probably not so much with a random guy. For example, if the date ends up being a disaster then she won't want that associated with her birthday. I would try to find an alternative, maybe you could ask her out for a smaller date during the week.
