On the timeline page, (Timeline.dumpshock.com), you can pull all the events for a given year.

If you don't specify any other criteria other than year, are the events sorted at all? are they in sequential order? If so, is there any way to get the dates of those events?

Select 'All Years'

don't select a country.

You will get everything in the timeline database in order of years.(takes a bit of time to load)

As for events for 1 year, I have no idea what order they are in.
