When using the function M + 1, what date does it calculate?

The function M + 1 is designed to calculate a date that is one month from the current date. In the context of scheduling and date manipulation, "M" typically represents the current month. Therefore, when 1 is added to M, it signifies the progression to the next month.

For example, if the current date is March 15, the calculation M + 1 effectively results in April 15. This makes it clear that the purpose of this calculation is to determine a date one month later, which is crucial in scheduling scenarios where one needs to plan events or appointments that occur on a monthly basis.

In contrast, the other choices describe time frames that do not align with the function. The current date, one week from today, and one year from today pertain to different durations and calculations, which do not reflect the specific purpose of M + 1 in date calculations related to months.
