get your clocks out, the festive season is about to begin
quote:
Ding-Dong

Today a great celebration will take place on Bells Island, for it is the Feast of Coincidus. On this island there is a monastery and a nunnery. At regular intervals (a whole number of minutes) the monastery bell dongs once. The nunnery bell rings at regular intervals too (different from the intervals of the monastery's bell, but also a whole number of minutes). So the island also regularly reverberates with a ding from the nunnery's bell. The Feast of Coincidus takes place whenever the monastery's dong and the nunnery's ding occur at the same moment, and that is exactly what is due to happen at noon today.

Between consecutive Feasts the dongs from the monastery and the dings from the nunnery occur alternately and, although the two noises only coincide on Feast days, they do occur a minute apart at some other times. When the bells coincided last time (at noon, a prime number of days ago) this whole island indulged in its usual orgy of eating and drinking.

How many days ago was that?


and best wishes to everyone over the festive season!

gtho4,

The citizens of Bells Island celebrate "The Feast Of Coincidus" every 1439 days.

It's a long time to wait for a good bit of fodder and a good drink.

Kindest Regards

Bannockburn
