A Clojure library that is a very thin wrapper around ical4j.
To create an empty calendar, call
(create-cal "Acme, Inc." "Acme Calendar" "V0.1" "EN")
which will return an object that, when converted to a string, produces a valid iCalendar with no events.

To create an event with a duration, call create-event with start date, end date, title, and keyword args for unique-id, description, url, location, and organizer url. Start date and end date are of type java.util.Date. Below, ->date is a utility method that converts an ISO8601 formatted date string to a java.util.Date.
(create-event (->date "2015-12-25T09:16:00-07:00")
(->date "2015-12-31T11:37:00-07:00")
"Family Vacation"
:unique-id "1234"
:description "Have fun."
:url "http://www.example.com/1234"
:location "1313 Mockingbird Lane"
:organizer "http://www.example.com")
One can also create an event that has a start time, but no duration. For this, call the function create-event-no-duration.
(create-event-no-duration (->date "2015-12-25T09:16:00-07:00")
"Let the dog out"
:unique-id "1234"
:description "Dog must go out"
:url "http://www.example.com/1234"
:location "1313 Mockingbird Lane"
:organizer "http://www.example.com")
To create an all day event, call create-all-day-event. The time portion of the start date argument will be truncated.
(create-all-day-event (->date "2015-11-16T09:16:00-07:00")
"Attend Clojure Conj"
:unique-id "1234"
:description "Clojure/conj is the original conference for Clojure and its community."
:url "http://clojure-conj.org/"
:location "Philadelphia, Pennsylvania USA"
:organizer "http://cognitect.com/")
To add an event to a calendar, call add-event!, passing in the calendar and the event.
(add-event! (create-cal "Acme, Inc." "Acme Calendar" "V0.1" "EN") event)
Finally, to print the output, call output-calendar, passing in the calendar, which will give an iCalendar compliant String.
(let [cal (ical/create-cal "Acme, Inc." "Acme Calendar" "V0.1" "EN")
ical-events (map #(ical/create-event %) events))
_ (reduce (fn [cal event] (ical/add-event! cal event)) cal ical-events)]
(ical/output-calendar cal))
The output should look similar to this
