will be helpful for those in need http://momentjs.com/ or https://date-fns.org/
From Moment docs:
code :
``````var a = moment([2007, 0, 29]);
var b = moment([2007, 0, 28]);
a.diff(b, 'days')   // =1
``````
``````a.diff(b, 'days')+1   // =2

To fix the issue you can do Would like to calculate number of days between two dates , for the below example, No of days == \$6-\$4 position. , one way to do that:
code :
`````` kent\$  awk -F, -v q='"' '{
c="date -d"q\$4q" +%s";c|getline d1;close(c);
c="date -d"q\$5q" +%s";c|getline d2;close(c);
printf "%s,%d\n", \$0,(d2-d1)/3600/24}' file

like below fixes the issue Hi am new in ruby on rails and jquery pickadate function is quite new for me. Functions are defined in amsul.ca/pickadate.js/
from read this site. I am just trying to implement my solution.
code :
``````    \$('#start_date').pickadate({
format: 'dd/mm/yyyy',
selectMonths: true,
selectYears: 25
}
});
format: 'dd/mm/yyyy',
selectMonths: true,
selectYears: 25
}
});
``````
``````var firstDay = new Date(\$( '#leave_start_date' ).val() ),
lastDay = new Date(\$( '#leave_end_date' ).val() ),
daysDiff = calcHolidays( firstDay,lastDay );
if ( isNaN( daysDiff ) )
\$( '#leave_days' ).val( "" );
else
\$( '#leave_days' ).val( daysDiff );
}
``````
``````function calcHolidays( dDate1, dDate2 ) {
var weeks, dateDiff, weekDay1, weekDay2;
if ( dDate2 < dDate1 ) return -1;
weekDay1 = dDate1.getDay(),
weekDay2 = dDate2.getDay();
weeks = Math.floor(( dDate2.getTime() - dDate1.getTime() ) / 604800000);
if ( weekDay1 <= weekDay2 )
dateDiff = ( weeks * 5 ) + ( weekDay2 - weekDay1 );
else
dateDiff = (( weeks + 1 ) * 5) - ( weekDay1 - weekDay2 );
return ( dateDiff + 1 );
}

it helps some times I need to create a query that will calculate the number of days between the cleared dates and uncleared dates and then calculate the total of those days. , You can use this.
code :
``````;WITH CTE AS
(
SELECT *,
RN = ROW_NUMBER() OVER (PARTITION BY Name, Status ORDER BY [Date])
FROM DataSet
)
SELECT
T1.Name Person,
SUM(DATEDIFF(DAY,T1.Date, T2.Date)) -1 [Number of Uncleared Days]
FROM CTE T1 INNER JOIN CTE T2 ON T1.Name = T2.Name AND T2.Status ='Cleared' AND T1.RN = T2.RN
WHERE T1.Status ='Uncleared'
GROUP BY T1.Name
``````
``````SELECT Person, SUM([Date_Diff]) - 1 AS [Number of Uncleared Days]  FROM
(
SELECT
D1.Name AS Person,
DATEDIFF(DAY, [Date] ,
(SELECT TOP 1 [Date]
FROM DataSet D2
WHERE D2.Status ='Cleared'
AND D1.Name = D2.Name
AND D1.Date < D2.Date) ) AS [Date_Diff]
FROM
DataSet AS D1
WHERE
D1.Status ='Uncleared'
) AS SubQ
WHERE
[Date_Diff] IS NOT NULL
GROUP BY Person

hop of those help? Convert both dates to the POSIXct class first. Be sure to do the calculations in the same timezone, the POSIXt classes default to your locale timezone, as.Date defaults to UTC.
