Add weeks to date
To add weeks to a date you can directly add the number of weeks to the formula, by multiplying by the number of days in a week, or apply the Excel DATE function
Example: Add weeks to date
|
=B5+C5*D5
|
This formula adds five (5) weeks to directly to the date specified in cell (B5), by multiplying the number of days in a week and the number of weeks you want to add to the date. This formula links to specific cells in the worksheet for the formula parameters, however, you can also enter the number of weeks you want to add and the date that you want to add the weeks to directly into the formula (e.g. ="15/03/2017"+7*5).

This formula adds five (5) weeks to the date specified in cell (B5),by multiplying the number of days in a week and the number of weeks you want to add to the date, using the Excel DATE function. This formula links to specific cells in the worksheet for the formula parameters, however, you can also enter the number of weeks you want to add and the date that you want to add the weeks to directly into the formula (e.g. =DATE(YEAR("15/03/2017"),MONTH("15/03/2017"),DAY("15/03/2017")+7*5)).

OBJECTS
Worksheets: The Worksheets object represents all of the worksheets in a workbook, excluding chart sheets.
Range: The Range object is a representation of a single cell or a range of cells in a worksheet.
Worksheets: The Worksheets object represents all of the worksheets in a workbook, excluding chart sheets.
Range: The Range object is a representation of a single cell or a range of cells in a worksheet.
PREREQUISITES
Worksheet Name: Have a worksheet named Analysis.
Weeks to add: This example references to cell ("D5") to source the number of weeks to add onto the date. Therefore, if using the same VBA code cell ("D5"), in the Analysis worksheet, must be populated with the value that represents the number of weeks you want to add to the date. You can also enter the number of weeks you want to add directly into the VBA code by replacing the cell reference (ws.Range("D5")) with the number of weeks.
Date: This example references to cell ("B5") to source the date that you want to add the weeks onto. Therefore, if using the same VBA code cell ("B5"), in the Analysis worksheet, must be populated with the date that you want to add the weeks onto. You can also enter the date directly into the VBA code by replacing the cell reference (ws.Range("B5")) with the date inside the double quotation marks (e.g. "15/03/2017").

ADJUSTABLE PARAMETERS
Output Range: Select the output range by changing the cell reference ("G4") in the VBA code to any cell in the worksheet, that doesn't conflict with the formula.
Weeks to add: Select the number of weeks that you want to add to the date by changing the value in cell ("B5") in the Analysis worksheet.
Date: Select the date that you want to add the weeks onto by changing the date in cell ("B5") in the Analysis worksheet.
