These are very interesting additions Eric and I'm in the process of having a play with things - apologies for the delay in commenting; I've been away without any connectivity and also had teaching.
So far, I've experienced difficulty using an end-date field in my local 'on this day' project - whenever I include one everything slows down and I get an alert that 'a web page is slowing down your browser' and I have to reload the page to regain control. This seems to happen even if I set the end-date to tomorrow. I guess this is something I've done to slow it down and I need to undertake further tests with your default 'It's About Time!' page. I also note that using a start-date and end-date in a timeline generates events for each year in the 'view all events' list of the Calendar settings. I guess this is inevitable but it means there are many events generated for each person or subject and, even in your project, there are over 300 events. Will this slow things down? For an 'on this day' project, it seems one would not want either a birth or a death event (say) to be listed in any year before that date so for Albert Einstein (Born: March 14, 1879; Died: April 18, 1955), no birth event prior to and including 1878 and death event prior to and including 1954. But each event would show thereafter for perpetuity. If I understand correctly, events would only display between the start-date and end-date when the fields are set. I appreciate an 'on this day' calendar would usually display just the current year so I'm wondering whether there is a way to remove options to go backwards or forwards in time so only the current year is shown. However, it might be interesting to see events change as the year changes - going backwards there are likely to be fewer events to display. For information, I'm using Windows 10/Firefox 81.0.1. Many thanks for all your work on this project, I'm learning quite a bit as I tinker around.
