In one of the Public Enterprise classes, Asst.Prof. Ramachandra from Osmania University made a light-hearted comment on how our Fiscal year starts on April fools day. =The height of coincidence.=
There is nothing to it, its a date. A convenient one.
The message is, India Fiscal Calendar starts 1st April of a year and ends on 31st March the following year.
If you were interested in findings, then Indian Agriculture year starts from July and ends June following year.
The Central Bank or Reserve Bank of India has its own calendar year starting from June and ending July the next year.
So it is never a 2017 or 2018 or 2019, and used always as 2017-2018, 2018-2019, 2019-2020.
This March 31st the Fiscal year of 2017-2018 will come to end in India.
