A quick and dirty script to rename files from the format "Sunday 25th February 2018.md" to the format "2018-02-25.md"

rename.py

import datetime
import os

files = os.listdir("journal/2019")

for file in files:
    if file == "images":
        continue

    a = file.replace("th", "")
    a = a.replace(".md", "")
    a = a.replace("st", "")
    a = a.replace("rd ", " ")
    a = a.replace("nd ", " ")
    d = datetime.datetime.strptime(a, "%A %d %B %Y")
    print(file)
    print(d.strftime("%Y-%m-%d.md"))
    os.rename("journal/2019/"+file, "journal/2019/"+d.strftime("%Y-%m-%d.md"))
