{daily.howto} How to tell if spring has arrived

Mathematicians:
S={days|days belong to spring}
if n(S)<>0 then it is spring. The abstraction is left for the reader as an excercise. We have an empty set in Edmonton.

Astro-physisists:
If the earth has completed on full turn round the sun, it is spring again. The reference for the start of the spring is its previous year. The first spring we can track, dates back to the big bang when t=0, where t is the time. It is spring in Edmonton.

Computer Scientist Wanna-Be's:

#define SPRING_TEMPERATURE 10 /* Unit is Celesius */

int isSpring( struct days day ) {
    if ( avg_temperature( day.temperature ) >= SPRING_TEMPERATURE )
        return 1;
    else
        return 0;
}

If you are in Edmonton, make the following change:
#define SPRING_TEMPERATURE 0 /* that's right, zero is the measure! */

It is not spring in Edmonton.

Humble man in the woods:
Burry the girl with April in her eyes after she died by your firelight. Check to see if flowers have grown on the grave. Because of that basterd who ordered his slaves to turn her away, it won't be spring in your area until next year. This is happening every year in Edmonton.


All right, all right!

You don't need math to tell when spring has arrived;
You can't trust the crazy computations in astronomy, either;
You don't need to write a program for everything;
You don't need to listen to old songs to figure things out;

You just need to go out and smell the freshness in air.
Not in Edmonton though. You will freeze everything in your nostrils.
