To get started, click on each tab along the bottom of the sheet to get an idea for what the data looks like.

Next, go to the Alignment TAB and set up a filter such as by location, site, or alignment type.

In the Dates TAB choose a date range to search for matches. Select matching dates for Sun columns in the SUN tab.

The same can be done in the VENUS and MOON tabs with some added complexities.
(Venus must be identified and is sometimes too close to the sun to see rising or setting, the Moon rise/set can be any time of day / night, etc.)

Also you can choose a single alignment to view in the Display TAB which will show all matching event dates.
