The following examples are for preventing unexpected results.
- Adding one month and six days to 25th September results in 31st October, not 1st November.
- Adding one month and four days to 29th June results in 2nd August, and then subtracting one month and four days to 2nd August results in 28th June, not 29th June.
- Adding one month to 30th and 31st August results in 30th September. The each results are the same date.
- Adding one month and seven days to 25th August and to 25th September results 2nd October and 1st November. But each number of days added are not the same. The first is 38 days, the second is 37 days.
When you edit two or more different dates by using the Backward/Forward function, you'd be better off to use a number of interval days.
