The WEEKDAY function in Excel is a useful tool for finding the day of the week for a given date. It helps you determine whether a particular date falls on a weekday (Monday to Friday) and, if so, which day of the week it is. This function can be handy for various applications, such as scheduling, project management, and more.

## Syntax

## How to use

The WEEKDAY function is quite straightforward to use. You provide it with a date in the **serial_number** argument, and it returns the day of the week based on the specified **[return_type]** (which is optional). Here are some examples to illustrate how to use it:

1 |
=WEEKDAY("2023-11-03") |

This formula will return 5 because November 3, 2023, is a Friday (assuming the default return type of 1).

1 |
=WEEKDAY("2023-11-03", 2) |

Using return type 2, this formula will return 6 because November 3, 2023, is a Friday, which is represented as 6 in this context.

1 |
=WEEKDAY("2023-11-03", 11) |

With return type 11, this formula will also return 6, indicating that November 3, 2023, is a Friday.

Remember to input your date in the proper format (in quotation marks), and you can use this function to determine the day of the week for various dates.

## Examples
