Alpha = 1 (1000)
Beta = 2 (2000)
Gamma = 3 (3000)
Delta = 4 (4000)
Epsilon = 5 (5000)
Digamma = 6 (6000)
Zeta = 7 (7000)
Eta = 8 (8000)
Theta = 9 (9000)
Iota = 10
Kappa = 20
Lambda = 30
Mu = 40
Nu = 50
Xi = 60
Omicron = 70
Pi = 80
Qoppa = 90
Rho = 100
Sigma = 200
Tau = 300
Upsilon = 400
Phi = 500
Chi = 600
Psi = 700
Omega = 800
Sampi = 900
So, 2013 should be
Beta (2000)
Iota (10)
Gamma (3)
2000+10+3=2013
That means it is "big"
