시간을 계산하는 방법

from datetime import datetime, timedelta

now = datetime.now()

# ago
edt_sec = now - timedelta(seconds=3)
edt_min = now - timedelta(minutes=3)
edt_hr = now - timedelta(hours=3)
edt_day = now - timedelta(days=3)
edt_week = now - timedelta(weeks=3)

# hence
edt_sec = now + timedelta(seconds=3)
edt_min = now + timedelta(minutes=3)
edt_hr = now + timedelta(hours=3)
edt_day = now + timedelta(days=3)
edt_week = now + timedelta(weeks=3)


# seconds, minutes, hours, days, weeks, months, years
from dateutil.relativedelta import relativedelta

edt_month = now - relativedelta(months=3)
edt_year = now - relativedelta(years=3)
