The previous answers are correct but it s generally a better practice to do   import datetime   Then you ll have  using datetime timedelta   date 1   datetime datetime strptime start date    m  d  y    end date   date 1   datetime timedelta days 10

In order to have have a less verbose code  and avoid name conflicts between datetime and datetime datetime  you should rename the classes with CamelCase names   from datetime import datetime as DateTime  timedelta as TimeDelta   So you can do the following  which I think it is clearer   date 1   DateTime today    end date   date 1   TimeDelta days 10    Also  there would be no name conflict if you want to import datetime later on

If you happen to already be using pandas  you can save a little space by not specifying the format   import pandas as pd startdate    10 10 2011  enddate   pd to datetime startdate    pd DateOffset days 5

Sometimes we need to use searching by from date  amp  to date  If we use date  range then we need to add 1 day to to date otherwise queryset will be empty  Example  from datetime import timedelta    from date    parse date request POST  from date     to date      parse date request POST  to date      timedelta days 1   attendance list   models DailyAttendance objects filter attdate  range    from date  to date

Generally you have got an answer now but maybe my class I created will be also helpfull  For me it solves all my requirements I have ever had in my Pyhon projects   class GetDate      def   init   self  date  format   Y- m- d            self tz   pytz timezone  Europe Warsaw            if isinstance date  str               date   datetime strptime date  format           self date   date astimezone self tz       def time delta days self  days           return self date   timedelta days days       def time delta hours self  hours           return self date   timedelta hours hours       def time delta seconds self  seconds           return self date   timedelta seconds seconds       def get minimum time self           return datetime combine self date  time min  astimezone self tz       def get maximum time self           return datetime combine self date  time max  astimezone self tz       def get month first day self           return datetime self date year  self date month  1  astimezone self tz       def current self           return self date      def get month last day self           lastDay   calendar monthrange self date year  self date month  1          date   datetime self date year  self date month  lastDay          return datetime combine date  time max  astimezone self tz    How to use it   self tz   pytz timezone  Europe Warsaw   - here you define Time Zone you want to use in project GetDate  2019-08-08   current   - this will convert your string date to time aware object with timezone you defined in pt 1  Default string format is format   Y- m- d  but feel free to change it   eg  GetDate  2019-08-08 08 45   format   Y- m- d  H  M   current    GetDate  2019-08-08   get month first day   returns given date  string or object  month first day GetDate  2019-08-08   get month last day   returns given date month last day GetDate  2019-08-08   minimum time   returns given date day start GetDate  2019-08-08   maximum time   returns given date day end GetDate  2019-08-08   time delta days  number of days   returns given date   add  number of days   you can also call  GetDate timezone now    time delta days -1  for yesterday  GetDate  2019-08-08   time delta haours  number of hours   similar to pt 7 but working on hours GetDate  2019-08-08   time delta seconds  number of seconds   similar to pt 7 but working on seconds
