What does CCYYMMDD date format mean?

Question

I want to speak to a soap service that has a date parameter which is required to be the CCYYMMDD format.

What is its definition?

Answer 1

CC in CCYYMMDD date format indicates how many centuries are finished for particular year

ex.

• year 90 has 0 centuries finished but it's placed in 1st century,
• year 1980 has 19 centuries finished but it's placed in 20th century,
• year 2018 has 20 centuries finished but it's placed in 21th century,

So CCYY is equal to YYYY but in another way of writing
