The, 144 as Days ^^

1440 ‘as minutes’ = 1 days … can also be called 4 Mayan Tun as 360 x 4
14400 as ‘minutes’ = 10 days … can also be called 40 Mayan Tun as 360 x 40
144000 as ‘minutes’ = 100 days … can also be called 400 Mayan Tun as 360 x 400
1440000 as ‘minutes’ = 1000 days … can also be called 4000 Mayan Tun as 360 x 4000
and all together in ‘minutes’, 
these are 1111 days

1440 'minutes' = 1 'day', can also be called 4 Mayan Tun as 360 x 4 = 1440

The Maya say a Tun is 360 'days'.  If this is the only translation... then
360 x 4 = 1440 would amount to 1440 'days'.

so if 1440 can be 'days', just like they count Baktun cycles of 144000 'days' x 13 cycles = 1872000 'days'
it can also be said

1440 'days' x 13 cycles = 18720 'days'
14400 'days' x 13 cycles = 187200 'days'
144000 'days' x 13 cycles = 1872000 'days' currently only known as the Mayan Long Count calendar cycle.
1440000 'days' x 13 cycles = 18720000 'days'

And...

1440 x 1300 = 1872000 'days'

N O P Q R S T U V W X Y Z = 260 
260 Tzolkin x 5 = 1300 x 1440 = 1872000 days is also known as December, 21, 2012
The winter solstice, the 'end' date of the current Mayan cycle... 

.................
and as a reminder

144 hours = six days
1440 minutes = 1 day

for a total of seven days, a week as we have them.
