In Help Mode, hover over input fields to learn more about them. On mobile devices, click on the input fields instead.

The Calculator Tab can be used to calculate all calendrical and astronomical data for a given date. Either the Long Count Date or the Calendar Round Date must be within their respecitve variable limit (3/2).
If the Long Count Date entered has 3 or less full variables (e.g. 12.3.*.*.*) the entered data will be used to calculate all dates:


							12.3.1.1.1
							12.3.1.1.2
							12.3.1.1.3
							...
							12.3.1.2.1
							12.3.1.2.2
							...
							12.3.2.1.1
							12.3.2.1.2
							...

The entered Calendar Round Date data will then be applied as a filter to the calculated Long Count Dates. E.g. if "Ahau" is entered as a Tzolkin Day Name, only Long Count Dates with that day name will be displayed in the results.

Enter multiple numerical values as a range (e.g. 1-3) or separated by a comma (e.g. 1,2,7), or combine both methods (e.g. 1,2,10-12).
Enter full variables either by leaving the field empty or with a '*'.
Skip through input fields using Tab/Shift-Tab.
