Somewhere around SnowLepoard iCal's default behavior changed. It used to be that If an event spanned midnight (e.g. 7p-7a) then in the Month view it would only show up on the day the event started.
Now in Lion, it produces a colored bar that spans both days with 'ends 7am' on the right hand side of the bar in the second day. In Month view this is annoying and clutters the display when you have several consecutive events that span midnight e.g. three 7p-7a events in a row.
How can I get the old behavior back without editing events as many of them are from calendar subscriptions?
