Lets Play with Date in Python....

Getting Fromated Time

localtime = time.asctime( time.localtime(time.time()) )
print "Local current time :", localtime

Output

import calendar
cal = calendar.month(2008, 1)

   How To Convert Date to DateTime

Example:

import datetime 
import dateutil.relativedelta 
from datetime import date, timedelta
date_from = obj.date_from//we are taking date(2014-6-11)
date_to = obj.date_to//date formate
date_from = datetime.datetime.strptime(obj.date_from, "%Y-%m-%d") 
date_to = datetime.datetime.strptime(obj.date_to, "%Y-%m-%d")

output
date_from = 2014-6-11 00:00:00

How Many Month Between Two Dates
1)first Convert date in to datetime objects(Refer previous)
2)Month = (12 * date_to.year + date_to.month) - (12 * date_from.year + date_from.month)

 


            
How To Print Current Date Time

from datetime import datetime

from dateutil.relativedelta import relativedelta

import time

from math import *

today_current_datetime = datetime.now().strftime('%Y-%m-%d %H:%M:%S')

today_current_datetime = datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S') 

Finding Days, Hours,Minutes,seconds between Two Dates

from datetime import datetime

from dateutil.relativedelta import relativedelta

import time

from math import *

start_date = task.work_id.date (Normal Date)

end_date = datetime.now().strftime('%Y-%m-%d %H:%M:%S') (current datetime)

duration = datetime.strptime(end_date, '%Y-%m-%d %H:%M:%S') - datetime.strptime(start_date, '%Y-%m-%d %H:%M:%S')

days, seconds = duration.days, duration.seconds

hours = days * 24 + seconds // 3600

minutes = (seconds % 3600) // 60

seconds = seconds % 60

hours_toupdate = int(hours) + (float(minutes)/60)

How To Add One Day To The Date

from datetime import datetime,date

from datetime import timedelta

production_date_planned_from = datetime.strptime(production_date_planned,"%Y-%m-%d") // production_date_planned normal date

production_date_planned_to = production_date_planned_from + timedelta(days=1)

How To add Months to Date

import datetime

import dateutil.relativedelta

from datetime import date, timedelta

date_from = obj.date_from (normal date)

date_from_str =str(date_from)

d = datetime.datetime.strptime(date_from_str, "%Y-%m-%d")

new_date= d – dateutil.relativedelta.relativedelta(months=int(7))//substracting 7 months

How Can I convert Datetime to Date

from dateutil.relativedelta import relativedelta

import time

from math import *

from datetime import datetime

production_date_planned_to =2014-08-17 00:00:00

date = production_date_planned_to.strftime('%Y/%m/%d')

2014/08/17

How can I find Periods From Date

period_pool = self.pool.get('account.period')

search_periods = period_pool.find(cr, uid, slip.date_to, context=ctx)

period_id = search_periods[0]

period_from_date_value = period_from_date_value.with_context().find(date_value)[:1]

period_id = period_from_date_value.id

Year start date and end date

start_date = date(date.today().year, 1, 1) date

end_date = date(date.today().year, 12, 31)

year_start_date = str(datetime.strptime(str(date(date.today().year, 1, 1)), "%Y-%m-%d"))

year_end_date = str(datetime.strptime(str(date(date.today().year, 12, 31)), "%Y-%m-%d")) date time

Getting Year from Datetime

leave.date_from.split('-')[0] year

leave.date_from.split('-')[1] month

leave.date_from.split('-')[0] day

How to get Current Date

fields.date.today()
