How these tools handle date ranges
Date-only calculations use calendar days. Date-time calculations use the time zone configured by your browser. Range Explorer returns summaries; List Generator returns individual values and limits generated lists to protect browser performance.
Generated values stay in your browser. TrueTool does not upload your selected dates or generated lists.
