The forward and backward date calculation tool can calculate the exact date at the time point of a specified date plus or minus how many days, how many months, how many years, how many hours, minutes, and seconds.
Suppose we need to know the number, time and day of the week after 10:9:10 on August 8, 2021.
Set the year, month, day, and time of the date, and then choose whether to add or subtract the date forward or backward, set the time unit and value that need to be increased or decreased, and then start the calculation.
According to calculations, it is 2021-08-09 10:18:10 after 1 day and 9 minutes at 10:9:10 on August 8, 2021.
