There's an infinitesimal amount of time between days. There was a year zero
- it was just called year one, rather like saying that a new-born baby is
one! That's why the Millenium Doom was finished over a year early and was
closed before it had been used for it's primary function.
Starting from zero has only come into use due to computers, where
counting from 0 means eight numbers can be defined by 3 bits.

A new born baby is not one, it is in it's first year.

They degrade relatively gracefully provided that you can shunt the heat
away from the junction fast enough. That is the *BIG* problem with
retrofitting them to existing luminaires. The entire light fitting has
to be redesigned to make it LED friendly or they will cook.

One thing that really puzzles me is why LEDs have not completely taken
over the job of lighting domestic fridges yet. Commercial supermarket
freezers have been using them for some time now.

The fridge-freezer we got around 6 months ago has an LED inside the
fridge. The manual says something to the effect that it should last
practically forever, but if it doesn't, you're stuffed because it's
not replaceable.
Fridge in my caravan has a LED light.

A new born baby is not one, it is in it's first year.

In China said baby is "one" - and it carrie son - basically everyone is
numerically one year older than they are in the UK. But they make up for it
by calling the ground floor of a block of flats floor 1.

Which just goes to show it's all totally arbitrary....

I never knew that, according to wickyp all ages increase on the lunar
new year, rather than on the birthday, so could a baby born the day
before the lunar new year be counted as 2 years old? Or are there
special rules for that? Sounds like racehorses ...

I think mathematicians started doing it before computers existed
(Peano axioms, for example).

I agree. It drives me nuts (just a little) when someone whose
birthday is a month after mine says "You're a year older than I am for
the next month." It's like saying that a 2 ft 11 in board is
sometimes a foot longer than a 2 ft 10 in one.

I blame the cardinals - they should never have been ordinated.
