Differentiate visually between time periods

[magicznyleszek]

There are some ideas for periods:

• decade: 10 years
• century: 100 years (10 * 10)
• millenium: 1000 years (10 * 100)
• decem millennium: 10000 years (10 * 1000)
• centum millennium: 100000 years (100 * 1000)
• epoch: 1000000 years (1000 * 1000)
• aeon: 1000000000 years

Most probably it would make sense to differentiate (or also add mark) decades, and then mark century and millenium changes.
