To find a relative date 28 days in the future from 31st of July, you can manually calculate the new date by adding 28 days to the current date. Begin by noting that July has 31 days. By adding 28 days to July 31, you can determine the future date. Starting with the known date, July 31, add 28 days.

Calculating forward from the 31st of July, adding 28 days would take you to 28th of August. To manually calculate this, simply add 28 days to the 31st of July. Since July has 31 days, counting from the 31st to the 28th of August would give you the date that is 28 days in the future.

So, counting 28 days ahead from the 31st of July would indeed lead to the 28th of August. The process involves basic arithmetic—adding the number of days in August required to reach the total of 28 days. By manually adding days to the starting point of July 31, you can accurately find the date 28 days in the future.
