| Rules: | Examples: |
| 1. to subtract a number of days from current date, use expression like [-NNd] | %dd[-1d]% |
| 2. to add a number of days to current date, use expression like [+NNd] | %ddd[+22d]% |
| 3. to subtract a number of months from current date, use expression like [-NNm] | %dm[-24m]% |
| 4. to add a number of month to current date, use expression like [+NNm] | %ddmm[+1m]% |
| 5. to subtract a number of years from current date, use expression like [-NNy] | %dmyy[-2y]% |
| 6. to add a number of years to current date, use expression like [+NNy] | %ddmmyyyy[+10y]% |
| 7. expression must be concluded in the same percent signs (%) that concludes date variables | %ddmm[-1d]% - correct expression
%ddmm%[-1d] - invalid expression |
| 8. expression must be specified after regular date variables | %dd[-1d]% - correct expression
%[-1d]dd% - incorrect expression |
| 9. you may use only one expression in each macro variable. |
%ddmm[-1m]% - correct expression
(one variable and one expression)
%dd[-1d]%%mm[-1m]% - correct expression
(2 variables, 1 expression in each variable)
%ddmm[-1d][-1m]% - incorrect expression
(2 expressions in one variable) |
