ICS

This is a Drupal 7 field module upgrade of CCK iCal.

This module is intended to be a drop-in solution to format a simple date as an .ics download.

If your needs are more complex have a look at iCal Module which is designed to tackle all of the elaborate use cases you are bound to come across. This project does not intend to meet anything but the most simple requirements.

If you are looking for this you'd probably be better served by addtocal
