A simple text based maya date calculator
This calculator is designed to be simple, lightweight, and resistant to becoming legacy. It aims to be simple and relies on only jQuery and bootstrap.
It is text-based to allow for easy data entry, and easy sharing of computations.
It will take "incorrect" values, and try to work with them, rather than enforcing strict base-20 values.
Columns can be hidden via the "View" menu.
At the most basic, the calculator will show the Calendar Round, and Lord of the night for a given Long Count Date.
Eg, 8.19.10.11.0 becomes 8 Ajaw 18 Yaxk'in 8.19.10.11. 0
If a Distance Number (prefixed with either + or -) is added after a
Long Count date, the calculator will compute the subsequent Long Count
date along with the Calendar Round.
Eg,
8.19.10.11.0
+7.13
becomes
8 Ajaw 18 Yaxk'in 8.19.10.11. 0
+ 7.13
--------------
5 Ben 11 Muwan 8.19.11. 0.13
Multiple Distance Numbers can be chained and intermediary Long Counts will be calculated.
If at any point a new Long Count is added, it will reset calculations from that point.
Comments can be added either on their own line, by prefixing the line with # or by suffixing a line with #
Eg,
# My Date calculations
8.19.10.11.0 # A long count date
+7.13 # A distance number
Calculations can be shared by copying the URL.
If provided with a partial Calendar Round (eg, 9 Ak'bal * Pax), all possible
calendar rounds will be output.
If provided with a partial Long Count and Calendar Round (eg, 9.10.*.5.* * Chikchan *Sip),
all possible combinations of calendar rounds and long counts will be output.
Navigate to https://drewsonne.github.io/maya-calculator/ and try to enter the following values one line at a time.
The last two lines demonstrate that the calculator will work with the values even if they are invalid and try to compute a real Long Count date.
8.19.10.11 # (1) A long count date
+7.13 # (2) A distance number
9.17.5.0.0
# (3) Do some calculations
-3.4
-1.0
+30.1.2
+1.1000 # (4) An 'invalid' distance number
# (5) An example of partial date matches.
9.10.*.5.* * Chikchan *Sip
