To specify that a year is BC/BCE use the minus sign. Note, that the minus should go before the year, not entire date. For example: <code>03.15.-44</code> is correct, and <code>-03.15.44</code> is not. Also note that even though we use the minus sign, we don’t use the astronomical year numbering system where 1 BC corresponds to year Zero, 2 BC to year -1 and so on. There is no year Zero on the Timeline, and minus simply means BC. For example year -44 is year 44 BC.

''Color'' - All events of a layer have the default color. So usually you don’t need to put anything in this field. However, if you need to give some events a different color, you put color index in this field. For this to work you need to have the needed color in the list of colours. More on that later. Also you can make the background of the time interval transparent by putting letter ’t’ into the Color field instead of an index.

Also you can make the background of the time interval transparent by putting letter <code>t</code> into the ''Color'' field. Let's see an example of events with transparent backgrounds:

''The Principate'', ''The Dominate'', and ''Western emperors'' are just time intervals with transparent backgrounds. This is how they are specified in the source text:
<blockquote><poem>
The Principate;Principate;;;01.16.-27;193b;t
The Dominate;Dominate;;;10.28.306;387;1t
Western emperors;Western Roman Empire;;;411;09.04.476;2t
</poem></blockquote>
 
Note that you can combine color index with transparency marker.
