Useful Information

Date format

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.

DD 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.
MMM Month given in three letters, abreviation of the English names: JAN, FEB, MAR, APR, MAY, JUN, JUL, AUG, SEP, OCT, NOV, DEC.
YYYY Year given in four digits. But beware, it is not Y10K safe...
