去年上周

now = datetime.datetime.now()
thisMonthStart = datetime.datetime(now.year-1, now.month, now.day) # 去年
endDate = thisMonthStart - datetime.timedelta(days=thisMonthStart.weekday() + 1) # 截至时间
startDate = thisMonthStart - datetime.timedelta(days=thisMonthStart.weekday() + 7) # 开始时间

6个月前

thisMonthStart = now - relativedelta(months=6)
endDate_180 = thisMonthStart - datetime.timedelta(days=thisMonthStart.weekday() + 1) # 截至时间
startDate_180 = thisMonthStart - datetime.timedelta(days=thisMonthStart.weekday() + 7) # 开始时间
