はじめに
うちのチームは、日本、イギリス、インドのマルチサイト開発しています。海外とやると、しばしばタイトルみたいにあっちの祝日忘れてて、「あれ、今日話せないのか、時差もあるし次話せるのは..... おぃ！」ってなって、リリース前は特にあせることがあるのでなんとかしたいですね。
ちょっと探したところ、GoogleカレンダーのAPIで祝日を取ってきてslackへってやってるのが多いですね。なんかめんどくさいんで、もっと簡単にやれないかなと思っていたところ、gcalコマンドでも各国の祝日とれることがわかりましたのでそれでやってみます。
Slackのリマインダ
要は、この形にすればslackはリマインドしてくれる。
/remind [@someone or #channel] "[what]" [when]
おなじみのこんな感じでリマインド。目立つように国旗もつけたい。
インストール
gcalをインストール。macでやってます。
mac-mini:~ brew install gcal

超ざっくり。+もawkの区切り文字として使われているので、過去の祝日は日数が表示されないという雑さ。今から未来の祝日しか通知されない、過去は振り向かない仕様。

書き直し
ちょっと最初のバージョンは雑すぎたので、書き直しました。過去の祝日は表示なし。日本だけじゃなくて各国の祝日を入れました。#channelを変更して使えます。
