It is, if the tempo is not too high, and one devices a method for counting.

At moderato, 1/4 = 120, 13/16 is performable counting on 2s and 3s. One example 
is Krivo Sadovsko horo (Bulgaria), 13 = 4+5+4, 4=2+2, 5 = 2+3:

Another is Ispayche horo, 13 = 3+2+3+2+3

At higher tempo, one may need to count on 3s, 4s, and 5s, especially when 
clapping hands:

This is a Leventikos, in video video, it is in 16 = 4+2+3+4+3, but the clap 
hands 4+5+4+3.

This Leventikos is also performed in 12 = 3+2+2+3+2, with quadruplets on the 3s
