4. Start a new post, or open the post that you want to embed the calendar into, and click the 'HTML' tab. Copy the PHP code for the calendar, and paste it into the post at the position you desire. You can also add any other HTML or CSS that you need.
Placing the Calendar in the Sidebar
5. Log into the WordPress admin control panel, then click 'Appearance,' and 'Widgets.'
6. Locate the 'Text' widget in the main area in the center of the screen, and drag it to the sidebar on the right. Move the text widget to the position you want it to be on the sidebar; to place it between two widgets simply hover in place for a seconds and the widgets will move to make room.
