Hi the same problem happened to me. If your have Icloud on your computer you can sign in and when you click oto your claendar they should still be there. Then plug in your Iphon with the usb cable and go to general, settingins then go into icloud and scroll down to storage and backup and click on that. it should restore what is on your computer.
hope it works for you
