Scenario
You do not have the HTML skill or time. Or your over-worked busy web colleague unable to support you in time. Your boss what a calender schedule since last week.

Try this

Use Google Calender. First sign up Google Calender. Update the event detail you want to share with your target audience and make it public. Next, insert Google Calender on your department/business unit webpage and you are done.

Step-by-Step
Go to My Calenders, click the little triangle on your right and select calender settings, you should see something like this

Scroll all the way down to Embed This Calendar and follow the instruction.

Issues

Problem I could forsee is that your marketing communication people might not want the Google logo appear on the calender.
