python generate dates between two dates

# python 3.x
import datetime
import pandas as pd
start = datetime.datetime.strptime("01-12-2021", "%d-%m-%Y")
end = datetime.datetime.strptime("07-12-2021", "%d-%m-%Y")
date_generated = pd.date_range(start, end)
print date_generated.strftime("%d-%m-%Y")

day difference between two dates in python

from datetime import date
d0 = date(2017, 8, 18)
d1 = date(2017, 10, 26)
delta = d1 - d0
print(delta.days)

python get dates between two dates

from datetime import datetime, timedelta

def date_range(start, end):
    delta = end - start  # as timedelta
    days = [start + timedelta(days=i) for i in range(delta.days + 1)]
    return days

start_date = datetime(2008, 8, 1)
end_date = datetime(2008, 8, 3)
    
print(date_range(start_date, end_date))

calculate days between two dates python

from datetime import date

startDate = date(2021, 7, 19)
endDate = date(2021, 11, 12)
delta = startDate - endDate
print(delta.days)

generate dates between two dates python

import pandas
pandas.date_range(sdate,edate-timedelta(days=1),freq='d')

Python Difference between two dates and times

from datetime import datetime, date

t1 = date(year = 2018, month = 7, day = 12)
t2 = date(year = 2017, month = 12, day = 23)
t3 = t1 - t2
print("t3 =", t3)

t4 = datetime(year = 2018, month = 7, day = 12, hour = 7, minute = 9, second = 33)
t5 = datetime(year = 2019, month = 6, day = 10, hour = 5, minute = 55, second = 13)
t6 = t4 - t5
print("t6 =", t6)

print("type of t3 =", type(t3)) 
print("type of t6 =", type(t6))

compare two dates python

>>> from datetime import datetime, timedelta
>>> past = datetime.now() - timedelta(days=1)
>>> present = datetime.now()
>>> past < present
True
>>> datetime(3000, 1, 1) < present
False
>>> present - datetime(2000, 4, 4)
datetime.timedelta(4242, 75703, 762105)

Difference between two dates and times in python

# Timedelta function demonstration
from datetime import datetime, timedelta

# Using current time
time_for_now = datetime.now()

# printing initial_date
print("initial_date", str(time_for_now))

# Some another datetime
new_final_time = time_for_now + 
                timedelta(days=2)

# printing new final_date
print("new_final_time", str(new_final_time))


# printing calculated past_dates
print('Time difference:', str(new_final_time - time_for_now))

python check date between two dates

# If you convert all your date to `datetime.date`, you can write the following:
if start <= date <= end:
    print("in between")
else:
    print("No!")
