How Can I Calculate the Start and End Dates of a Week Given its Week Number and a Wedding Date?

Determining Week Start and End Dates from Week Number

The provided query calculates the number of wedding dates per week based on specific criteria. To enhance this query, we seek to determine the start and end dates of each represented week in the results.

Solution:

To obtain the week start date and week end date from the week number, it is necessary to consider the day of the week corresponding to the wedding date. The following SQL statements can be added to the query:

DATEADD(dd, -(DATEPART(dw, WeddingDate)-1), WeddingDate) AS WeekStart

DATEADD(dd, 7-(DATEPART(dw, WeddingDate)), WeddingDate) AS WeekEnd

By calculating the day of the week (dw) and subtracting (or adding) the appropriate number of days to the wedding date, we can obtain the corresponding week start and end dates. The current date and time components are ignored by using the DATEADD function.

Example:

Assuming the WeddingDate is '2023-05-12', which is a Friday, the following results would be obtained:

WeekStart: '2023-05-08'
WeekEnd: '2023-05-14'

This customization allows for additional insights into the weekly distribution of wedding dates, enabling deeper analysis and comprehensive insights.
