What does the expression {today}-{lastdate} calculate?

The expression {today}-{lastdate} calculates the number of days from today to the last update, making it useful for assessing the time elapsed between the current date and a previous date designated as "lastdate." This arithmetic expression specifically focuses on the difference in days between these two dates, providing a straightforward metric for understanding how much time has passed since the last recorded event or update. The result will be a numerical value indicative of the days separating the two dates, which can assist users in time-sensitive tasks, reporting, or tracking progress in relation to various activities or records.

This focus on a day count distinguishes this calculation from more complex time measurements, such as those involving hours or weeks, which are addressed in other choices but are not applicable to this particular expression. By concentrating solely on days, the expression serves a specific and clear purpose within the context of date comparisons and interval assessments.
