b'ak'tun
a 400-year chunk of time that the Mayans used to count time the hard way, without modern stuff like clocks or phones.
The b'ak'tun was the Mayans’ way of counting time before they had clocks.
I’d rather have a phone than deal with the b'ak'tun.
The Mayans didn’t need a phone, they had b'ak'tuns.
