How to manual date calculate?
Important: here is perfect formula of date calculate. nowadays, many websites and applications using this formula. today i explain some right formulas.
let's start
suppose
today date = 25-11-2020 and birth date = 11-06 -2000 [ used formet: dd-mm-yy ]
today date = 25-11-2020
birth date = 11-06-2000
if have birth date smaller from today date so use simple minus method.
Note here today's date months and years larger from birth date month and year.just like
today date : 25 - 11 - 2020
birth date : - 11 - 06 - 2000
Use minus method : ----------------
your age = 14 - 05 - 0020
There are different rules for the other type of date.
if have today's month smaller than the birth month so use this method.
for example date formats [dd-mm-yyyy]
today date = 23-06-2020
birth date = 19-11-2000
today month=06
birth month=11;
Days = today date-birth date;
for date Calculation
days= 23(today date)-19(birth date)
days = 23-19 = 4 ; Total days = 4 ;for the month Calculation md= 12(total month of year)-11(birth month); total month= md+(today month;)
12-11 = 1 ; 01+06 = 7 ; Total month = 7 ;for year Calculation today year of date- birth date of month
today date = 2020 birth date = 2000 2020-2000 = 20 ; Total year = 20;Note here today's months smaller from birth month.

birth date = 19-11-2000
age = today date-birth date ;
Total Year= age/1000×24×60×60×365.25
