DATE lookup table (1990/01/01:2041/12/31)

Question

I use a DATE\'s master table for looking up dates and other values in order to control several events, intervals and calculations within my app. It has rows for every single day

Answer 1

OK, so I tested my app using 31 days/month to calculate interest rates & pawnshops are happy with it! Local Law prays as follows: From pawn or last int. pymt. date to 5 elapsed days, 5% interest on principal, 6 to 10 days = 10%, 11 to 15 days = 15%, and 16 days to 1 "month" = 20%.

So the interest table is now defined as follows:

NUMBER OF ELAPSED DAYS SINCE
PAWN DATE OR LAST INTEREST PYMT

 FROM     TO  ACUMULATED
  DAY    DAY    INTEREST
-----   ----  ----------
    0      5       5.00%
    6     10      10.00%
   11     15      15.00%
   16     31      20.00%
   32     36      25.00%
   37     41      30.00%
   42     46      35.00%
   47     62      40.00%

   [... until day 90 (forfeiture allowed)]
   from day 91 to 999, daily prorate based on 20%/month.

Did something bad happen in the UK on MAR-13 or SEP-1752?
