v18.6 [Feb 4, 2015]
Enhancements and improvements in V18.6 are listed below.
New Baha'i Calendar
The traditional Baha'i calendar is being replaced by a new astronomical calendar with effect from sunset on March 20, 2015. Tabulated data for the new calendar has also been released for Baha'i years 172 to 221 (roughly 2015 to 2064 in Gregorian years). These changes have been incorporated seamlessly into Calendar Magic by continuing to use the traditional Baha'i calendar for Baha'i years before 172 and after 221. When further tabulated data is available for Baha'i years beyond 221, a further adjustment will be made.
When listing Baha'i religious festivals, the situation is similar except that the upper cut-off point is now Gregorian year 2064 rather than 3000. This also applies to any Baha'i contribution to "On This Day".
Equation Solver
Added an Equation Solver to the list of Mathematical Utilities. This new utility will currently find all the roots of any quadratic, cubic or quartic equation with real coefficients. Other types of equation may be added later, depending on user feedback.
Prime Calculator
When assessing whether or not a given number is prime, the Baillie-PSW Primality Test is now used via YAFU.
Blood Alcohol Content (BAC) Calculator
The BAC limit in Scotland has changed from 80 to 50 mg per 100 ml of blood. The rest of the United Kingdom remains unchanged.
As a result, England, Northern Ireland, Scotland and Wales are now treated separately in the BAC Calculator. A side effect is that any BAC Calculator "sticky" country value may need to be respecified.
Global Distances
Distances between locations are now calculated more accurately using formulae which assume that the shape of the Earth is an ellipsoid of revolution rather than a sphere.
World-wide Locations Database
At the request of a user, added Mukilteo in Washington State, USA to the Calendar Magic locations database. Also added Makkum in the Netherlands.
