If you ever need a paper copy of your calendar, you can print a month, a day, or any date range you choose.
- Open Google Calendar on a computer.
- At the top of the page, click Day, Week, Month, or Agenda to choose which view to print.
- Use the arrows at the top to go to the first day, week, or month you want to print.
- In the top right corner, click More, then Print.
- On the Print Preview page, you can change the date range, font size, page orientation, and color setting.
- When the preview looks right, click Print.
A window with print options for your computer will open and you can make more changes to your print settings. You'll probably need to click Print again.
