[ruby] 祝日判断や休日判断をrubyでやるなら、これでいいんじゃないかな - メモ

business_time gem

bokmann/business_time

business_time gemが便利そう。
このgemを使うと、Dateに対していろいろなmethodが使えるようになる。

[4] pry(#<Date>):1> Date.new(2015,1,2).workday?
=> true
[5] pry(#<Date>):1> Date.today.workday?
=> true
[6] pry(#<Date>):1> Date.today.weekday?
=> true
[7] pry(#<Date>):1> Date.today.monday?
=> true

# 特定の日付までの営業日を計算
[8] pry(#<Date>):1> Date.today.business_days_until(1.month.since)
=> 21

• 創立記念日などの、会社独自の祝日もカスタマイズ可能

BusinessTime::Config.holidays << Date.parse('会社独自の休みなど')

• config fileも作れる

rails generate business_time:config

• configに日本の祝日リストを持っておけば、判断methodを別途作成しなくても、Dateに生えるのが便利

business_time:
  beginning_of_workday: 9:00 am
  end_of_workday: 5:00 pm
