title: Combine (hour, minute, am/pm) columns for two times, then calculate minutes elapsed
body: <p>I have Time In and Time Out that need to be input on a google sheet. It has to be tracked down to the minute so I have a column for hour, minute, and am/pm. My goal is to have the amount of minutes elapsed between the time in and time out in a row. </p>
  
  <p>I have not found a way to combine all three columns into a time, especially with the am/pm column in the mix. Then subsequently do a formula to find minutes elapsed. I am not well versed in spreadsheet formulas so if there is an easier way of achieving my goal please let me know.</p>
  
  <p>A screenshot is attached of the google sheet columns. Thank you to anyone that can help.</p>
