Linking Cells to Google/Outlook Calendar

Good Evening,

I have attached a sample excel file that I need help with. We have a referral program at my job and if someone brings a new employee in they get cash after 30,60,90 & 120 days. What I am wondering is if once a date is entered into the spread sheet is there anyway for that date to be added to my calendar? Google calendar or Outlook.

Thanks in advance
