If the calibrations were on a schedule, shouldn't Sked have handled that? I was in the Navy as well. I've made countless databases, batch files, and VBScript just to automate and streamline tasking that the Navy refused to let you use non-gov tools like web apps and whatnot. I even created a fully finctioning VTC scheduling web application running on IIS and using classic ASP with a bootstrap/jQuery front-end for one of the bigger numbered fleets. This was in 2016. When they are all you reallly have, you can do wonders with the MS Office suite.
