In this guide, we will delve deep into the intricacies of the WEEKDAY function, ensuring that by the end, you’ll be wielding it with confidence and precision.

## When to Use the WEEKDAY Function

The WEEKDAY function serves a fundamental purpose – it allows you to retrieve the day of the week from a given date. This can be invaluable in scenarios where you’re dealing with time-sensitive data, such as scheduling events, analyzing trends, or simply organizing information chronologically.

## Syntax

`=WEEKDAY(date, [type])`

• date – The date for which to determine the day of the week. Must be a reference to a cell containing a date, a function returning a date type, or a number.
• type – [ OPTIONAL – 1 by default ] – A number indicating which numbering system to use to represent weekdays. By default counts starting with Sunday = 1.
• If type is 1, days are counted from Sunday and the value of Sunday is 1, therefore the value of Saturday is 7.
• If type is 2, days are counted from Monday and the value of Monday is 1, therefore the value of Sunday is 7.

7. Consider Locale Settings: If you’re working with dates in different locales, be aware that the behavior of the WEEKDAY function may vary. Adjust the locale settings in Google Sheets accordingly.
9. Test with Sample Data: Before applying the function to a large dataset, test it with a small sample to ensure it’s producing the desired results.
