@arivu96 is right. Make sure you calculate the financial year. You will need to do that in another workflow where you send as an argument the current date, and it returns back the period, week, and year.
Typically, a financial year is 13 periods with 4 weeks each and equals 364 days. Then, it will depend on when your year starts. Some companies always start on July 1st. Others (like in the USA) will start on the first Sunday before January 1st. So determine the first day of the current financial year, then you can figure out the last day of that year by adding 364 days, and thus knowing which year the current date lands in.
My head hurts thinking about it though. Maybe someone can help with a calculation. Essentially, if you have Dec 30, 2019 or Jan 1, 2020, you should get back a year of 2020, since the first day for 2020 would be July 1st 2019.
