how many times does a person breathe in a day
17,280-23,040 per day. A normal respiratory rate is somewhere around 8-14 breaths per minute. Given 1,440 minutes in a day, and assuming a normal respiratory rate of say 12 breaths per minute, and that respiratory rate doesn't vary much throughout the day, you'd have 12 * 1,440 = 17,280 breaths in a day.
