datewrkdy

Date of future or past workday

Syntax

EndDate = datewrkdy(StartDate,NumberWorkDays,NumberHolidays)

Description

EndDate = datewrkdy(StartDate,NumberWorkDays,NumberHolidays) returns the serial number of the date a given number of workdays before or after the start date.

Any input can contain multiple values, but if so, all other inputs must contain the same number of values or a single value that applies to all.

For example, if StartDate is an n-row character array of date character vectors, then NumberWorkDays must be an N-by-1 vector of integers or a single integer. EndDate is then an N-by-1 vector of date numbers.

If StartDate is a serial date number or date character vector, EndDate is returned as a date number. Use datestr to convert serial date numbers to formatted date character vectors.

If StartDate is a datetime array, then EndDate is returned as a datetime array.

Examples

Determine the Date for a Future Workday

Determine the EndDate for a future workday using a date character vector for StartDate.

StartDate = '20-Dec-1994';
NumberWorkDays = 16;
NumberHolidays = 2;
 
EndDate = datewrkdy(StartDate, NumberWorkDays, NumberHolidays)

EndDate = 728671

datestr(EndDate)

ans = 
'12-Jan-1995'

Determine the EndDate for a future workday using a datetime array for StartDate.

EndDate = datewrkdy(datetime('12-dec-2000','Locale','en_US'), 16, 2)

EndDate = datetime
   04-Jan-2001

Determine the EndDate for future workdays using a vector for NumberWorkDays.

NumberWorkDays = [16; 20; 44];
EndDate = datewrkdy('12-dec-2000', NumberWorkDays, 2);
datestr(EndDate)

ans = 3x11 char array
    '04-Jan-2001'
    '10-Jan-2001'
    '13-Feb-2001'
