Eras
The eras browser and converter let you browse through the most common Classical world
eras or convert values among the most used chronological systems.
Use these pages to browse or
convert eras (Olympic years, ab urbe condita, Byzantine era,
etc.), just convert between Roman and Arabic numbers, or get a Roman emperor from a year
or vice-versa.
Roman Calendar and Emperors
Here you will find a perpetual Roman calendar and an interactive list of Roman emperors.
The Roman calendar allows you to browse a Roman
calendar for any year and month. The emperors list allows
you to browse all the Roman emperors, and filter them according to any portion of their
titles. This is useful when you want to quickly find all the emperors matching a full
or partial titolature, e.g. coming from an inscription.
Measurements
Here you can find a converter for all the commonest measurement units of the Classical
world.
Convert between measurements from Egypt, Greece and Rome: linear, surface, weight
and capacity measurement units; metrical and US systems, Egyptian royal and Ptolemaic cubitus,
Greek, Attic, Doric (Phidonic), Spartan, Sicilian, Italic, Roman and Eastern Imperial systems,
Alexandrian and Roman itinerary systems.
Historical Dates
Here you can test a sample implementation of complex historical datations.
Expressing dates in digital archives of ancient world objects: inscriptions, artifacts
etc. can be tricky to define in terms of their chronology in a both human- and
machine-readable way. Here you can experiment with a
real-world sample expressed with XML.
Numeric Systems
Play with a converter for Attic, Mylesian and Roman numeric systems.
A tiny Silverlight application allows you to convert between Attic, Mylesian and Roman
numeric systems. Just type the number in the desired format and click the Convert
button to have it converted into all the other formats.
