A really dedicated reader who goes by the name of postal has actually gone to all the trouble of making the March, 2009 Calendar of Architectural Events available in the Google calendar format, which you can access here. Once there, you can import individual events into your own Google calendar.
postal also put the calendar into ics format . . .
. . . so you can import it en masse into your own Google calendar, or into iCal or, possibly, Outlook 2007. (If anyone does the Outlook import successfully, let me know.) In iCal, of course, it can be placed in its own calendar or integrated with one that already exists. You can download the ics formatted calendar here.
My thanks to postal. for taking the substantial amount of time it took to create these calendars. It's deeply appreciated.
Now I'm looking to you, dear readers, to let me know whether this is a feature you would like to see with each month's calendar.
