date_popup calendar picker for event start/end dates?

Probably not without modification.

what about using javascript tools module and the JS calendar JS?

Which one specifically?

I would also like to see the default being a date picker. I have added a content type and it displays and works, but there is no way of removing the drop down lists so have two areas for selecting the event date! Confusing in the extreme, so had to remove the preferred date picker.
Could this be added to the next update as the module rocks, just needs some tweeks to make it invaluble.

see datepicker.module in contrib

How do I use the date picker module with Events? I installed the required .js and .css files but it still forces me to use the standard entry fields.

You should see a link that says "select start/end date" below the normal forms.

Don't you see them?

I do but they're not pop-ups. Just drop down lists.

This is the link I meant.

First image shows the link, the second the popup

Oh I see! Thanks - I completely missed that.

The Select End Date link shouldn't be visible if the event doesn't have one.

Made a new bug report from your observation.
