@Savechilds, you could do it as outlined in this post discussed previously:

Calculate number of days between 2 dates

@luswetiopicho, you could have a look at the sample shared below, the exact copy of what @Xiphware has outlined above: In the survey tab of your XLSForm: [Image 1] Data entry screen as seen in Enketo: [Image 2] Reference XLSForm: Calculate Days.xlsx (10.3 KB)

Hi¡ Kal I hope you are well.
I have a question if I already have a field calculated with the days and then I must calculate based on those days, how many months correspond to said days including 0 if it is less than 30 days how would I calculate it?
For example if i have as result in field calculate days 45 for default show me 2 months

thanks in advance for your support
