Last Found Date (Search=>Filter=>Dates)
Use these fields to select waypoints based on the date of the last found log entry for the waypoint. By default, all waypoints are selected (on or before today's date). Use the drop-down menu to select other date options. The second field allows you to choose the date to apply: the default is today's date. Click on the calendar icon
to display a calendar, or type a date directly into the field in the format of your system's date setting. GSAK displays a second calendar field if you choose "Between (inclusive)" on the drop-down menu.If you want to compare relative dates rather than absolute dates, then use the during options. For example, "Show me caches found in the last 7 days"
This filter gives you an indication of recent geocaching activity in the current database.
If you want to compare to another date use the Compared to option.
