date-difference

Below query is my sql server query and I want it to convert it into hive query: select DATEDIFF([minute], '19000101', '2013-01-01 10:10:10') You could use unix_timestamp for dates after 1970 : SELECT (unix_timestamp('2013-01-01 10:10:10') - unix_timestamp('1970-01-01 00:00:00'))/60 Convert both dates to seconds from 1970-01-01 Substract them Divide by 60 to get minutes EDIT: Adding Minutes: change date to unixtime -> add var * 60sec -> convert back to date SELECT from_unixtime(unix_timestamp('2013-01-01 10:10:10') + 10 * 60) AS result db<>fiddle demo using MySQL 来源： https://stackoverflow.com

I have two date columns and trying to measure days between the two dates excluding weekends. I'm getting a negative number and need help solving. Table CalendarDate DayNumber FirstAssgn FirstCnt DayNumber2 Id BusinessDays 5/21/2017 Sunday 5/21/17 5/21/17 Sunday 1 -1 Query: TRUNC(TO_DATE(A.FIRST_CONTACT_DT, 'DD/MM/YYYY')) - TRUNC(TO_DATE(A.FIRST_ASSGN_DT, 'DD/MM/YYYY')) - ((((TRUNC(A.FIRST_CONTACT_DT,'D'))-(TRUNC(A.FIRST_ASSGN_DT,'D')))/7)*2) - (CASE WHEN TO_CHAR(A.FIRST_ASSGN_DT,'DY','nls_date_language=english') ='SUN' THEN 1 ELSE 0 END) - (CASE WHEN TO_CHAR(A.FIRST_CONTACT_DT,'DY','nls_date

I want to subtract dates in 'A' from dates in 'B' and add a new column with the difference. df A B one 2014-01-01 2014-02-28 two 2014-02-03 2014-03-01 I've tried the following, but get an error when I try to include this in a for loop... import datetime date1=df['A'][0] date2=df['B'][0] mdate1 = datetime.datetime.strptime(date1, "%Y-%m-%d").date() rdate1 = datetime.datetime.strptime(date2, "%Y-%m-%d").date() delta = (mdate1 - rdate1).days print delta What should I do? Assuming these were datetime columns (if they're not apply to_datetime ) you can just subtract them: df['A'] = pd.to_datetime

I'm wondering if there is some new and awesome possibility to get the amount of days between two NSDates in Swift / the "new" Cocoa? E.g. like in Ruby I would do: (end_date - start_date).to_i Emin Buğra Saral The accepted answer won't return the correct day number between two dates. You have to consider the time difference as well. For example if you compare the dates 2015-01-01 10:00 and 2015-01-02 09:00 , days between those dates will return as 0 (zero) since the difference between those dates is less than 24 hours (it's 23 hours). If your purpose is to get the exact day number between two

I know there are lots of questions on SO about how to get, but I want and example using new Java 8 Date api. I also know JodaTime library, but I want a work way without external libraries. Function needs to complain with these restrictions: Prevent errors from date savetime Input are two Date's objects (without time, I know localdatetime, but I need to do with date instances) syntagma If you want logical calendar days , use DAYS.between() method from java.time.temporal.ChronoUnit : LocalDate dateBefore; LocalDate dateAfter; long daysBetween = DAYS.between(dateBefore, dateAfter); If you want
