-------------------------------------
| 「システム管理者感謝の日」は毎年やってきます。
| 「システム管理者感謝の日」はいつなのか？が気になりますよね。
| 毎年7月最後の金曜日なので、毎年、日にちが少しづつ違っています。
| そこで、未来の「システム管理者感謝の日」を調べるスクリプトをpython で作成しました。
| これなら、100年先、200年先の「システム管理者感謝の日」を調べることが可能です。
| 以下がそのスクリプトです。2000年から、500年分の「システム管理者感謝の日」を表示します。
python スクリプト
^^^^^^^^^^^^^^^^^^^^^^^^^
.. code-block:: python
:linenos:
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import datetime
import locale
# 2000年から、200年分の「システム管理者感謝の日」を調べる。
# 以下のようにして、実行して下さい。
# > python.exe .\checkSAD.py
# d = datetime.date(1970, 1, 1) # UNIX歴の最初の日をスタートとする。
d = datetime.date(2000, 1, 1) # 2000/1/1を検索のスタート日とする。
LastFriday = datetime.date(2000, 7, 6) # 最初の「システム管理者感謝の日」
LastDay = datetime.date(2200, 12, 31)
while LastDay > d:
if d.month == 7 : # 7月 で、金曜日であれば、その日を記録する。
if d.weekday() == 4 : # 0 : 月曜日, 1 : 火曜日, 2 : 水曜日, 3 : 木曜日, 4 : 金曜日, 5 : 土曜日, 6 : 日曜日
LastFriday = d
if d.month == 8 : # 8月 になった時点で、記録されている日が7月最後の金曜日
if None != LastFriday:
print(LastFriday.strftime("%Y-%m-%d %A"))
LastFriday = None # この変数を初期化して、次の年の「システム管理者感謝の日」に備える。
d = d + datetime.timedelta(days=1)
