Bring up my month calendar that' on my galaxy s3 on the computer so i can copy the information

Hi is it the S planner app you talk about?
I found that S Planner uses several calendars. You can have one in the samsungaccount. Open Splanner app. In menu press MENU button (left bottom), select calendars. Now you have a whole list. facebook, gmail, samsung. I started initially using (and adding things) to my samsung calendar. But I soon found that the samsung was difficult to use. So I changed to using the gamil calendar and reentered birthdays etc. Now with the gmail calendar it is synced at all times and you can access and edit your calendar in PC when logging in to gmail, you select calendar. In to right corner you find a small grey with nine little blocks. This is apps. In here you go to calendar. Hope it helps. Stop using the Samsung account calendar! I guess if you want to access this on pc you must log into your samsung account on pc. I didnt because I switched to gmail calender. Best regards
