Excel WORKDAY.INTL function
Returns the date a number of work days later, with a weekend of your choice. In Spanish Excel it is called DIA.LAB.INTL.
Syntax
English Excel
=WORKDAY.INTL(start_date, days, [weekend], [holidays])
Spanish Excel (Mexico)
=DIA.LAB.INTL(fecha_inicial, días, [fin_de_semana], [días_no_laborables])
Spanish Excel (Spain, Latin America)
=DIA.LAB.INTL(fecha_inicial; días; [fin_de_semana]; [días_no_laborables])
| Argument | What it is |
|---|---|
| start_date | The starting date. |
| days | How many work days to add (negative subtracts). |
| weekendoptional | Which days are off, as in NETWORKDAYS.INTL. |
| holidaysoptional | A range with the holidays. |
Example
NETWORKDAYS and WORKDAY assume Saturday and Sunday off. Their .INTL versions accept another weekend: 11 is Sunday only, 7 is Friday and Saturday, or a text such as "0000011" (1 = day off, Monday to Sunday). The last argument is the holidays.
=WORKDAY.INTL(B2,15,11,$G$2:$G$4)
Common mistake
The result is a serial number: format the cell as a date if you see something like 45678.
