analyze_ordinal_error_create(options)

Find the errors between conversion between badi dates to JD and vice versa. This tests the BahaiCalendar.badi_date_from_jd() method. Both the jd_from_badi_date() and badi_date_from_jd() methods default to the the time zone in Tehran.

-b Also if -S and -E are used they must be used together and refer to Badi years.

analyze_ordinal_error_list(options)

Find the errors between the Badi datetime ordinals and the Python date time ordinals.

-a

analyze_timestamp_errors(options)

Find the errors in timestamp conversions to Badi dates. This test tries to ensures that the badidatetime.date.today() method changes date on sunset based on local time. https://www.unixtimestamp.com

-c with -A, -O, -Z, -D, and optional -U (seconds instead of minutes)

analyze_timestamp_for_today(options)

See if we get close to the correct time after sunset so we can prove that sunset can be found with a timestamp.

-t -S and -E in Gregorian years

check_dates(options)

Check for correct dates between different methods.

-d with -S and -E (Gregorian) -A -O -Z

test_ordinals(options)

Check that the ordinals are correct.

-o with -S and -E

test_sunset_flip_invariant(options)
