Clojure Business Day Calculator

Simple library for end date calculation. Add minutes to start date considering defined work schedule.

How it works

Configure your business days schedule into def or map and pass it to main function:

(def business-work  {:monday
                     {:include true
                      :sched ["08:00" "18:00"]}
                     :tuesday
                     {:include true
                      :sched ["08:00" "18:00"]}
                     :wednesday
                     {:include true
                      :sched ["08:00" "18:00"]}
                     :thursday
                     {:include true
                      :sched ["08:00" "18:00"]}
                     :friday
                     {:include true
                      :sched ["08:00" "18:00"]}
                     :saturday
                     {:include false
                      :sched ["08:00" "12:00"]}
                     :sunday
                     {:include false
                      :sched ["09:00" "18:00"]}})

You must include all the days and define the days you want to include for calculation.

{:monday {:include true :sched ["08:00" "18:00"]}
 :tuesday {:include true :sched ["08:00" "18:00"]}
 ...
 :saturday {:include false :sched ["08:00" "18:00"]}
 :sunday {:include false :sched ["08:00" "18:00"]}
}

If configuration is :include false, the schedule will be ignored, so anything will be accepted.
