There are a few different ways that you can change the appearance of your Google Calendar. You can change the colors of your calendar, the way your events are displayed, and even the font size.
To change the colors of your calendar, click the "Settings" cog in the top right corner of your calendar. Then, click "Edit colors." From there, you can change the colors of individual parts of your calendar, including the background, text, links, and calendar grid.
To change the way your events are displayed, click the "Settings" cog, then click "View options." From there, you can choose to show events in day, week, or month view. You can also choose how many days you want to show in each view, and whether or not you want to see event times in your calendar.
To change the font size, click the "Settings" cog, then click "General." Under the "General" tab, you'll see an option for "Font size." Click the drop-down menu and select the font size you want to use.
