How to read time intervals in ISO8601 format
This dataset uses custom time intervals format for periods, YYYY-MM-DDT00:00:00/PnI, where P tells that this is period; n is the number of intervals and I is interval type which can be Y(year), M(month), W(week), D(day). For example, from April 2019 to March 2022 is represented as 2019-04-01T00:00:00/P3Y, which can be read as '3 years period starts from 1st of April 2019 and ends on 31st March 2022'.
