Yes of course there are solutions for your issue, just a question, do you want to always create a Date variable for current year +1 or your issue only concerns the 31st of march?

first create a variable: variable = [%CurrentDateTime%]
then a year variable for this year: year = formatDateTime($variable,'YYYY')
check if today is "a" 31st --> if formatDateTime($variable,'dd-MM') = '31-03'
if the exclusiv split is true create a variabe for the 31 of the next year
nextDate = parseDateTime('31-03-'+( parseInteger($year) + 1),'dd-MM-yyyy')
and then do your action
for the condition if, use exclusiv splits or java
