(require [java-time :as jt])

(defn date-range
  "returns a sequences of dates between start and end (exclusive)"
  [start-date end-date]
  (let [dates-from-start (jt/iterate jt/plus start-date (jt/days 1))]
    (take-while #(jt/before? % end-date) dates-from-start)))

;; returns a random date between 2018 and 2020
(rand-nth (date-range (jt/local-date 2018 1 1) (jt/local-date 2020 1 1)))
