Although it's a good day for going out and having fun, the person you ask might not want to go.
It's a good day to go out and have some fun and let your hair down today, however, you may find that the person you especially wanted to spend some quality time with is not in the mood. Do not try to push this person, as it will only cause friction between you, respect their feelings and find someone else to have fun with, you have plenty of friends who'd love to help you party.
