A month is a good time to sex livebearers if they are growing on the average.

The larger livebearers usually don't start showing secondary sex characteristics until about 3-6 months of age. Guppies are about 4 to 6 weeks when this happens.

some of my platys don't differentiate into male until they are 6-7 months old. Platys are very slow growers compared to guppies, as doggydad says.

I would wait until they're about 1.5 cm or so. Then look to see if they have the gonopodium.
