Subtract a year or 12 months from current date i.e. today()

Hi @Ayub

I think you could try subtracting the number of days (365). Useful functions are here

Form Operators and Functions

I suggest you also check this post as it might have some relevant information

Calculate date with number

I find it easier to reason about the year and the month/day separately: concat(int(format-date(today(), ‘%Y’)) + (50-${age}), format-date(today(), ‘%m%d’)) That would be the correct expression if the service was provided today. You probably need to use the service date both to calculate the age and the components of the expiration date. To compute a date N weeks from now: format-date(date(decimal-date-time(today())+(N * 7)), ‘%Y%m%d’) Same as above, you'll need to use the service date rathe…

Best,
Andrea
