Two thousand twelve was a five. The sum of its numerals. Pentagrams have five points. Two thousand and thirteen, is a six. Bee honeycombs have six sides. Insects, not arachnids, have six legs.

Of the two images here, the above is how the Brahmins from India described six.

For Mayans, 1 was a pebble, 5 was a stick, 6 was a pebble and a stick.
