My only concern is that the reflection doesn't fade away, making it so that there's an ugly cut-off line on transparent cells, so try a fade on the transparency. But thanks so much for making a Google Calendar logo, I've been bumming around without one for a long time since I can never find a high-res image of the logo.

Found a high-res logo (after searching the inter-tubes for like, an hour) and made some logos with it.
