Calendar period measuring tool on D1 chart for Gann analysis

 
Does anyone know of a tool that on a Daily chart can give a calendar day (not trading day) measurement similar to MT4's candle count tool in crosshair mode. Something that can measure calendar days by a mouse click on a start candle and dragging forward or backwards in time to a target candle. This would be very useful to me for Gann cycle analysis. Thanks.
