A simple library to check if a date is a holiday.

Add the following to your sbt build (Scala 2.12.x):

libraryDependencies += "com.github.sameerparekh" %% "holidays" % "0.1.1"

• Import the library.
• Configure an implicit holiday list (HolidayList)
• Check your LocalDate to see if it is a holiday.

import com.github.sameerparekh.holidays._
import org.joda.time.LocalDate

implicit val holidayList: HolidayList = USAFederalHolidays

println {
  if (LocalDate.now().isHoliday) "Today is a holiday" 
  else "Today is not a holiday"
}

Pull requests welcome.

• Create a new instance of a HolidayFromYear, which is a function from a year to a LocalDate. A number of helper functions are available.

• Create a new instance of a HolidayList, which is a set of HolidayFromYear.
