dateweekday

dateweekday is a function commonly found in spreadsheet software and programming languages that calculates the day of the week for a given date. It typically returns a numerical representation of the day, where specific numbers correspond to specific days. For instance, in many systems, 1 might represent Sunday, 2 Monday, and so on, up to 7 for Saturday. The exact numbering scheme can sometimes vary depending on the software or programming language's regional settings or default conventions.

The primary purpose of dateweekday is to enable users to easily identify the day of the week associated with any specific calendar date. This is useful for a variety of applications, such as scheduling, analyzing trends based on the day of the week, or performing date-related calculations. When used in spreadsheets, it often takes a date value as an argument and returns the corresponding day of the week. In programming, it serves a similar function, allowing developers to manipulate and interpret dates within their code. The output can then be used in conditional logic, data sorting, or for display purposes. Understanding the numerical output and potential variations in its mapping to days of the week is crucial for accurate use.
