Today, it's usual to specify days. For example you have to keep some gov
papers for 90 days. This seems to come from computers era. In our minds,
however, we immediately think 90 days=3 months.
For example, one may want to delete some files older than 9 months. It's
far more intuitive than 270 days.
When we talk about years it is still going. For example I need to keep
my receipts for 5 years because IRS audits.
Accepting this, it's intuitive, for example, that 3 months before July,
31 is April, 30.
The same happens for the years. 5 years before February, 29 is February, 28.
Again, this is my opinion and that's the way I like it :-)
What makes sense depends on where you're looking from.
It's 28 February, you need to keep it for 5 years, therefore you could
reason that you can dispose of it on 28 February, 5 years hence.
However, that happens to be a leap year.
Should you still have it on 29 February?
