What is a WEEKDAY Function?
The WEEKDAY function in Google Sheets is a useful tool that returns the day of the week corresponding to a date. It can be particularly helpful for scheduling, planning, and analyzing data based on days of the week. The function can return a number representing the day, which can be customized to start the week on different days.
In simpler terms, WEEKDAY allows you to determine which day of the week a specific date falls on, making it easier to organize and interpret your data.
A Practical Example
Imagine you are tracking project deadlines and want to know which day of the week each deadline falls on:
Deadlines Table:
| TaskID | TaskName | Deadline |
|---|---|---|
| 1 | Project A | 2023-10-02 |
| 2 | Project B | 2023-10-05 |
| 3 | Project C | 2023-10-07 |
You want to find out the day of the week for each deadline.
WEEKDAY Formula
To achieve this, you would use the WEEKDAY function as follows:
EXCEL
In this formula:
C2is the cell containing the Deadline date.- The second argument
1specifies that the week starts on Sunday (1 = Sunday, 2 = Monday, ..., 7 = Saturday).
Result of the Formula
When you apply the WEEKDAY formula to the Deadlines Table, the output would look like this:
| TaskID | TaskName | Deadline | Day of Week |
|---|---|---|---|
| 1 | Project A | 2023-10-02 | 2 |
| 2 | Project B | 2023-10-05 | 5 |
| 3 | Project C | 2023-10-07 | 7 |
In this case, the WEEKDAY function returns:
- 2 for Monday (October 2, 2023)
- 5 for Thursday (October 5, 2023)
- 7 for Saturday (October 7, 2023)
Why Use WEEKDAY?
