unparse giving wrong result

sonwh98 commented 8 years ago

(ns foo
  (:require [cljs-time.format :as f]
                 [cljs-time.coerce :as c]))

(def date-formatter (f/formatter "MM/DD/YYYY"))
(defn str->date [date-as-str]
  (->> date-as-str (f/parse date-formatter) c/to-date))

(defn date->str [date]
  (->> date c/from-date (f/unparse date-formatter) ))

(-> "06/23/2016" str->date date->str) ;;evaluates to "06/175/2016" when the original  "06/23/2016" is expected

Am I using unparse incorrectly? why does it give "06/175/2016" and not "06/23/2016"?. I am using [org.clojure/clojurescript "1.9.76"]

used moment.js instead

(require  [cljsjs.moment])

(defn str->date [date-as-str]
  (let [m (-> date-as-str (js/moment. "MM/DD/YYYY"))]
    (. m toDate)))

(defn date->str [date]
  (.. (js/moment. date) (format "MM/DD/YYYY")))

The pattern DD means day of the year. Lowercase dd is what you want for day of month.
