It’s funny!Is for all …… which want to know when you have a critical day.
Use any knowledgeto be succesful in what you do. Of course , this depend only of you.
External human factors can introduced only if you know birthdays from max.3person (in this app).

The novelty is that I have an idea how to change /the real number of days lived so far/.
By ex.: if you borned in Romania , Buzau and after from data1 to data2 you will be in France,Paris or in other place from the world , the
change must be made , and after can work with the model (theory of biorhytm 1897-1902 Hermann Swoboda, Wilhelm Fliess, Alfred Teltscher).

Hence must compute this differences for all 7 components:
/primary/physic cycle(18days) , social(28days) , intellectual(33days) ,
/secundary/ spiritual(53days) , awarness(48days) , aesthetic(43days) , intuition(38days).

If you . When you travel by air you cross times zones. The totaleror=howcycle()*difference_time_zones.
After must real_days=ndays+totaleror. must consider and sign from est towest must plus , from west to est must minus.
Here , this is only initial model…may be in a future new model with influence…

I think that genetics machine is not influenced by diseases or age because we have same DNA in all life , from born to death…

And, in finally, is very good to know why you have a bad day …";
