sum date + month
Bonjour à tous,
J'aimerais faire une somme entre 2 colonnes (date et mois).
Voici un exemple ci-dessous :
Comment je pourrais créer une nouvelle colonne qui aurait pour résultat la somme des deux colonnes et donnerait : "02/09/2024".
La colonne date est en format date j/m/a et la colonne time est en format "mois" avec la personnalisation des formats.
Merci pour votre réponse.

Re: sum date + month
The formula is
If( Month( :date ) + Num( :"time (month)"n ) <= 12,Date MDY( Month( :date ) + Num( :"time (month)"n ), Day( :date ), Year( :date ) ),Date MDY( (Month( :date ) + Num( :"time (month)"n )) - 12, Day( :date ), Year( :date ) + 1 ))

Re: sum date + month
You can try using Date Increment() , but you might have to modify your month value (it seems to be character in your case, so use Num() to convert it in a formula).
Names Default To Here(1);
dt = New Table("TEST (4)",
Add Rows(1),
Compress File When Saved(1),
New Column("time", Numeric, Continuous, Set Values([4]), ),
New Column("date", Numeric, "Continuous", Format("d/m/y", 12), Input Format("d/m/y"), Set Values([3797452800]), )
);
dt << New Column("a", numeric, continuous, Format("d/m/y", 12), Formula(Date Increment(:date, "month", :time, "actual")));
It might also be important to check how your solution works in possible corner cases (Date Increment(31Jan2024, "month", 1, "actual"))

Re: sum date + month
There is no "month" function, likely because months have varying lengths. So I took a brute force approach to create a formula, but I believe it will work. Look at the New Date column in this file. But @txnelson 's approach is MUCH better! I had forgotten about the Date MDY function!

Re: sum date + month
Bonjour,
Votre réponse fonctionne pour ajouter les mois. Mais lorsque la somme de la date + le mois dépasse l'année en cours, on obtient un problème (pas de résultat ou l'année ne devient pas l'année +1) :
Ici, le résultat de la colonne "somme" devrait être : 02/05/2025
Comment peut-on contourner ce problème ?
Merci pour votre réponse.
