Magento

A calender so customers can select a delivery date and if possible a timeslot.

I need this too ... 

This is exactly what I need. Not so much a time slot, but definitely a delivery date.
I would also like to disable weekend delivery in the calendar or charge extra for weekend delivery.

YES! YES! YES! Please… it would really help to get a calendar AND to be able to block out Sundays (who wants to deliver on Sundays anyway). I love Magento BUT I’m afraid it’s really of no use to me without a calendar feature

This feature will be quite useful for me too, do the admin know if this is going to get released in the next version?

Yup - I need this as well.

Yes Please desperately need, this....

Maybe if some one can explainme where need that date control, I can try with some example.

For me when you checkout - and your at shipping you then get a date control asking what date/time you would like the.

see this thread - http://www.magentocommerce.com/boards/viewthread/5504/

* Shipping is free (flat rate of 0.00)
* Tomorrow + following 7 days available to select if current time is before 4pm
* Day-after-tomorrow + following 7 days if current time is 4pm or later
* Sundays must be skipped
* Saturdays are given a £25 premium price
* Public holidays must be skipped

Has anyone figured out how to do this yet??  I need the same thing for my site.

Why hasnt anyone developed an extension for this… i reckon it would be a hit!!

I don’t think that anyone figured it out. At least - I don’t know of any working solution. If anyone has it - please, please - let us know. 

Yeah its good option at checkout, due to lack of this feature we developed customize solution for a client, so if Magento offers we can use Magento next time.
