Automatically Run a Macro so Many Seconds, Minutes, or Hours After an Excel Workbook has been Opened

Run a macro after a certain amount of time has passed since the Excel workbook was opened. This means that you can set this macro to run another macro after the Excel workbook has been open for 10 seconds, 25 minutes, 1 hour, etc. This allows you to run times sensitive macros in Excel, such as time based warnings - i.e. "You have 15 minutes left for this test!" As it is now, this macro will run another macro 10 seconds after the Excel workbook that contains this macro is opened.

This macro only calls another macro in Excel. This means that you have to already have another macro which you need this macro to run at a set time length. Also, this workbook must go in the "ThisWorkbook" window for macros and not a module. In order for this macro to work, you must save and close and then reopen the workbook after this macro has been installed in the workbook. This is because this macro is triggered to run by the opening of the workbook in which it is contained.

This macro uses the Application.OnTime method in Excel. In order to modify the macro for your needs, just change Name_of_Macro to the name of the macro which you want to run. Make sure the name is exactly the same and include any require parameters for the other macro if that is needed.

Also, you need to setup the macro to run the other macro at the time interval that best suits your needs. To do this, simply change 00:00:10 in the macro below. As it is this macro will run another macro 10 seconds after the workbook is opened. The first set of zeros is for hours; the next set is for minutes; the last set if for seconds.

Where to install the macro:  ThisWorkbook
