Best Answer - Chosen by Asker:
second
minute (60 seconds)
hour (60 minutes)
day (24 hours)
month (about 30 days)
year (a little more than 365 days)
decade (ten years)
century (100 years)
millenium (1000 years)
era (as defined by a political or social movement)
eon (a very long unspecified amount of time)
For periods longer than that you usually talk about thousands or millions of years. As you can see, these time categories are not always that exact.
