WORKDAY.INTL

The WORKDAY.INTL function in Excel is used to calculate the next working day after a specified number of workdays have been added to a start date. This function is particularly useful for scheduling tasks, project management, and tracking deadlines in business contexts.

Syntax 🔗

=WORKDAY.INTL(start_date, days, [weekend], [holidays])

start_date The initial date from which to begin counting workdays.
days The number of workdays to add to the start_date to determine the resulting date.
weekend (Optional) An optional parameter that specifies which days of the week are considered as weekend days. It uses a 7-character string (1 for non-working day, 0 for working day) where the order starts from Saturday to Friday. Default is 1 (Saturday and Sunday are weekends).
holidays (Optional) An optional range or array containing the list of dates considered as holidays when calculating workdays. These dates are not counted as workdays.

About WORKDAY.INTL 🔗

When navigating through work schedules and project timelines in Excel, turn to WORKDAY.INTL for precise and efficient date calculations. This function offers a straightforward solution for determining deadlines, project completion dates, or scheduling appointments based on workdays, excluding weekends and designated holidays, allowing for accurate tracking of important timelines and deliverables in professional settings while ensuring optimal time management strategies are implemented effectively.

Examples 🔗

Suppose you have a project starting on June 1, 2022, and it has a duration of 5 workdays excluding weekends (Saturday and Sunday) and holidays. You want to calculate the project's completion date using a specified list of holidays. The WORKDAY.INTL formula would be:

=WORKDAY.INTL("06/01/2022", 5, 1, {"07/04/2022", "09/06/2022", "11/25/2022"})

This will return the date 5 workdays after June 1, 2022, considering the provided holidays.

Consider a scenario where you have a task that starts on August 16, 2022, and requires 10 workdays for completion while excluding Fridays and Saturdays as weekends. No holidays are observed during this period. The WORKDAY.INTL formula would be:

=WORKDAY.INTL("08/16/2022", 10, "1010011")

This will provide the date that is 10 workdays after August 16, 2022, accounting for the designated weekends.

Notes 🔗

When using the WORKDAY.INTL function, ensure that the start_date is inputted as a valid Excel date. The days argument represents the number of workdays to advance from the start_date. The weekend parameter defines which days are considered as non-working days. If not specified, it defaults to Saturday and Sunday as weekends. The holidays parameter allows for the exclusion of specific dates from workday calculations.

Questions 🔗

How does WORKDAY.INTL differ from the WORKDAY function?

WORKDAY.INTL expands upon the capabilities of the WORKDAY function by allowing users to specify non-standard weekend parameters, such as considering different days as weekends (e.g., Wednesday and Thursday) or incorporating multiple days as weekend days.

Can I use WORKDAY.INTL to calculate project deadlines with custom weekend configurations?

Yes, WORKDAY.INTL enables users to customize the weekend parameter to define unique weekend configurations. This flexibility is advantageous when project timelines require non-traditional weekend definitions beyond the typical Saturday and Sunday setup.

How are holidays factored into workday calculations with WORKDAY.INTL?

The holidays parameter in WORKDAY.INTL allows users to input a range or array of holiday dates, which are then excluded from workday calculations. This feature ensures accurate scheduling by accounting for specific non-working days, such as public holidays or corporate shutdown periods.

Can I combine the use of holidays and custom weekend definitions in the WORKDAY.INTL function?

Yes, users can integrate both holiday dates and custom weekend configurations when utilizing the WORKDAY.INTL function in Excel. By incorporating these elements, individuals can create precise workday calculations that align with unique working schedules and holiday observances within their organization.
