Find oldest/youngest datetime object in a list

Oldest:

oldest = min(datetimes)

Youngest before now:

now = datetime.datetime.now(pytz.utc)youngest = max(dt for dt in datetimes if dt < now)

python datetime compare

Given a list of dates dates:

Max date is max(dates)

Min date is min(dates)

python datetime compare

Datetimes are comparable; so you can use max(datetimes_list) and min(datetimes_list)
