please see this date example :

114313
114327
114336
114357
115005
115011

What dates are those numbers supposed to be?

[#3]

this should be a date .

[Gysbert_Wassenaar]

Which date?

[#5]

it should be like this 114298  to   25/10/2014, ........

[#6]

in this case i try this

((date(yearstart(makedate((((SLTRDJ - fmod(SLTRDJ,1000)) / 1000) + 1900))) + (fmod(SLTRDJ,1000) - 1)) as Date,)

but when i need to convert a normal date to a numeric value it not converted .

Isn't it the same question that I answered here: Re: Date & Calender

The solution was

=date(makedate(left(SLTRDJ,3)+1900) + right(SLTRDJ,3)-1)

[#8]

yes l know ,

but

i need to convert the normal date to numeric value with the same logic that i get the date .

what i mean  is revers the the formula to get the numeric value .

because i face an issue after convert it when i try to join the date withe the other table but have normal date and i need to trust after convert the date to the numeric value is the same so can any one help me in this.

when i convert 25/10/2015 give me 41937 but in my database is 114298 ?! i don't know way ?!

If you want the reverse operation, convert a date to the number in the same format as above, this should work:

=year(date)-1900 & (date - yearstart(date))+1
