# Minimize the use of date strings and numbers.
# NEVER used naive datetime objects.
# Frequently check if the tzinfo is correct or cast the zone.
# - Delete variables that aren't supposed to be used anymore.
# - Functions should be short.
# - Do not pass ConfigParser objects around.
# - Use meaningful variable names.
# - Always write type hints.
# - Use the logger! Try not to print.
