Every show cave, mine or subterranea on this site has a short list
of hard facts called Useful Information.
With a contemporary browser it will be displayed like this text, with
smaller font and darkgreen letters on white background.
In the Useful Information block you find information in a very brief form, which makes some explanation necessary.
It is very difficult to write dates, fees and hours in a well readable manner, so we always tried to find a sort of "international" way of writing it, which should be understood by anybody. But if you do not understand it, here is the explanation:
Dates are always given in a very simple format: DD-MMM-YYYY. This is a date format similar to that on international flight tickets. The original IATA format goes DDMMMYYYY, we have added the hyphens to make it easier to read.
|Day given in two digits. If we have no accurate date, only month and year, we use the format MMM-YYYY. There is no way to mix up month and day, as the month is given in letters.
|Month given in three letters, abreviation of the English names: JAN, FEB, MAR, APR, MAY, JUN, JUL, AUG, SEP, OCT, NOV, DEC.
|Year given in four digits. But beware, it is not Y10K safe...
