My puppy just turn three months. I gave her a bath during the day. She appeared to sleep more after giving her a bath. She slept for the entire day. Then she plays at night She plays more at the night time. If I give her at bath at night will that reverse this behavior and allow me to sleep at night. During the night she keeps on barking and begging to play. I want to see her play but is there someway that I can have her sleep during the night and play during the day.

It could be the bath that has calmed her. But it could be her schedule. Are you home in the day time? If not, she probably sleeps while you are gone, and then is up all night. If you are home I would suggest playing with her a lot during the day, and taking her for a few walks during to day to tire her out so that she sleeps at night, like you.

I work in the day and when I get home I play with my puppy and take her for walks... we run around the house chasing each other, not only does it wear her out, but I get my exercise too!!

You need to take her on a lengthy fast paced walk in the evening first, and then have some play time after that, to drain any remaining energy. Puppies have a load of energy, so you need to spend a good hour at LEAST before bedtime, and your pup should start to know when bedtime is, and sleep through the night.
