  2. 4. if you want the number of days between the date range, you can get this as pd.DatetimeIndex(start='2010-01-01',end='2010-01-15',freq=us_bd).shape[0] – tsando. Sep 15, 2017 at 15:52. 1. The "start" and "end" arguments from the DatetimeIndex have been deprecated, but you can use len(pd.date_range(start='2010-01-01',end='2010-01-15',freq=us ...

If you want Monday to Tuesday to count as 1 day, just remove the "+ 1" after the first DATEDIFF. Then you'll also get Fri->Sat=0, Fri->Sun=0, Fri->Mon=1. – Joe Daley. Apr 4, 2011 at 1:11.

  4. Business days should be stored in a table in a database and served thru an API, there is no way to calculate business days. Holidays vary in countries, even in the USA each state may have different holidays, each company may have different business days

  5. T-SQL get number of working days between 2 dates

    stackoverflow.com/questions/14749877

    The above will only work if your dates are within 2047 days of each other, if you are likely to be calculating larger date ranges you can use this: SELECT Date1, Date2, WorkingDays. FROM @T t. CROSS APPLY. ( SELECT [WorkingDays] = COUNT(*) FROM ( SELECT [Number] = ROW_NUMBER() OVER(ORDER BY s.number)

  6. 15. I need to get the difference in days between two dates in DB2. I tried a couple of different queries but nothing seems to be working. So basically what i need to get is something like this. SELECT DAYS (CURRENT DATE) - DAYS (DATE(CHDLM)) FROM CHCART00 WHERE CHSTAT = '05'; I know that if I remove CHDLM and specify a date like '2012-02-20' it ...

  7. t : Total number of days between dates (1 if min = max) a + b : Extra days needed to expand total to full weeks. k : 1.4 is number of weekdays per week, i.e., (t / 7) * 5. c : Number of weekdays to subtract from the total. m : A lookup table used to find the value of "c" for each day of the week. Culture.

  8. For example, in the following example, the time difference between the two datetimes is 5 hours and if we use timedelta.days to get the number of days, that difference becomes 0 days or -1 day depending on which datetime was subtracted from which. Given the difference is less than 24 hours, this difference should probably be 0 days.

  9. First check how many days you got in the holiday table, excluding weekend days. Get business days (MON to FRI) between the 2 dates and after that subtract the holiday days. create or replace. FUNCTION calculate_business_days (p_start_date IN DATE, p_end_date IN DATE) RETURN NUMBER IS.

  10. Number of days between 2 dates, excluding weekends

    stackoverflow.com/questions/3615375

    The function np.busday_count counts the number of valid days between two dates, excluding the day of the end date. If end date is earlier than the begin date, the count will be negative. For more on np.busday_count read the documentation here. import numpy as np np.busday_count('2018-04-10', '2018-04-11')

  11. Yes, definitely. If you are studying long ranges, and you only need to exclude weekends (but not holidays), I expect it would be faster to construct a custom function that uses the days of the week for A and B and their total difference in time to compute the number of business days. –
