I'm not sure if something similar to this query is the right approach, or if I'm way off.Would you like to answer one of these unanswered questions instead?In Microsoft Access 2003/XP/2000/97, I have a database which contains a date field called Transaction Date.There are several ways to add dates in Excel depending on what exactly you want to do.For example, do you want to enter a today's date in some report or invoice?Or, perhaps you want to insert a date in Excel that will update automatically and always display the current date and time?Or, maybe you want to auto fill weekdays or input random dates in your worksheet?
See how to insert today's date and current time as static time stamp or dynamic values, how to auto populate a column or row with weekdays, and how to auto fill random dates in Excel.
Upon further reflection, if you desire a hardcoded timestamp, which is only updated by actions not including such things as open workbook, print, etc.
you could create a macro attached to worksheet_change. Value = Text(Now(), "yyyy/mm/dd HH:mm:ss") on the Worksheet_Change event.
You can type a date in an Excel cell in a variety of ways, for example 1/1/2015, or 1-Jan-2015, or 1-Jan, or January 1, 2015.
When you type something like that in a cell, Microsoft Excel knows you are entering a date and automatically applies the date format to that cell.
