How can I find out the hours in a date range? I'm currently calculating and printing the dates between two given dates.
from datetime import timedelta as td, datetime d1 = datetime.strptime(start_date, '%Y-%m-%d') d2 = datetime.strptime(end_date, '%Y-%m-%d') def get_delta(d1, d2): delta = d2 - d1 return delta delta = get_delta(d1,d2) for i in range(delta.days + 1): print d1 + td(days=i)
2016-04-22 2016-04-23 2016-04-24 2016-04-25 2016-04-26 2016-04-27 2016-04-28 ...
2016-04-22 00:00:00 2016-04-22 01:00:00 2016-04-22 02:00:00 2016-04-22 03:00:00 2016-04-22 04:00:00 2016-04-22 05:00:00 2016-04-22 06:00:00 2016-04-22 07:00:00 ...
You are incrementing the time by days and not hours,
timedelta(days=i) and not
from datetime import timedelta as td, datetime start_date = '2016-01-01' end_date = '2016-01-02' d1 = datetime.strptime(start_date, '%Y-%m-%d') d2 = datetime.strptime(end_date, '%Y-%m-%d') def get_delta(d1, d2): delta = d2 - d1 return delta delta = get_delta(d1,d2) for i in range(delta.days * 24 + 1): print d1 + td(hours=i)
2016-01-01 00:00:00 2016-01-01 01:00:00 ... ... 2016-01-01 23:00:00 2016-01-02 00:00:00
How to calculate the time interval between two time strings, Yes, definitely datetime is what you need here. Specifically, the strptime function, which parses a string into a time object. from datetime import The Duration Calculator calculates the number of days, months and years between two dates.
For readability, to have a clear semantics of what happens in the edge cases, you could define
date_range() function that is similar to the builtin
def date_range(start, end, step): while start < end: yield start start += step
from datetime import datetime, timedelta HOUR = timedelta(hours=1) def parse(date_string): '''Parse *date_string* in the %Y-%m-%d format.''' return datetime(*map(int, date_string.split('-'))) for dt in date_range(parse(start_date), parse(end_date), HOUR): print(dt)
end_date + ' 00:00:00 is not present in the output.
date_range() behaves like
end is not included. You could pass
parse(end_date) + HOUR to include the
8.1. datetime — Basic date and time types, A duration expressing the difference between two date, time, or datetime instances Calendrical Calculations, where it's the base calendar for all computations. Left bound for generating dates. end str or datetime-like, optional. Right bound for generating dates. periods int, optional. Number of periods to generate. freq str or DateOffset, default ‘D’ Frequency strings can have multiples, e.g. ‘5H’. See here for a list of frequency aliases. tz str or tzinfo, optional
If you look at the python docs for timedelta objects:
Only days, seconds and microseconds are stored internally
So if you want to get the hours you'll have to convert it from the seconds.
for i in range(delta.seconds / 3600 + delta.days * 24): print d1 + td(seconds=3600 * i)
How to calculate a time difference in minutes in Python, How do I get the time difference between two dates in Python? The Time Duration Calculator will calculate the time that has elapsed/difference between two dates with time.
Try something like this:
import datetime d1 = datetime.datetime(2016, 4, 28) d2 = d1 + datetime.timedelta(days = 2) delta = (d2 - d1).total_seconds()/3600 for i in range(int(delta)): print(d1 + datetime.timedelta(hours=i))

Python Tutorial, If you are just start using Python, working with dates and time values to calculate time Duration: 3:18 Posted: Aug 5, 2019 Even I searched in Google a lot, I couldn’t find an easy method to calculate hours between two times in Python. Finally, after a long time of research I got some code which helped to find days between two dates, then I sat for sometime and wrote a script which gives hours minutes and seconds between two dates. Here is the script:

The datetime Module We will be learning about the following classes from … Continue reading Python 101: Working with Dates and Time →
- What is get_delta()? Are d1 and d2 datetime.datetime objects or datetime.date objects?
- Won't this always go through the entire last day, rather than only to the hour in end_date?
- Yes, it will. I just tried to stay as close as possible to the original code snippet.
- Fair enough. And I suppose as long as the OP sticks with getting the dates from the format '%Y-%m-%d' it won't be an issue. Figured I'd point it out though.
- @MaximilianPeters this will go through entire days only, what if we wanted to go to the end_date's hour? thanks
- @Eric I am not sure if I understood your question correctly but you could add the hour to your
end_dateand adjust the
datetimeobject format accordingly. Is this the same question? stackoverflow.com/questions/52841611/…
