7. Combine DATE & SEQUENCE Functions to Increment Month

You can combine the DATE and SEQUENCE functions for incrementing months by 1. You can also get only the incremented month names with this function. To do the task, follow the steps below.

  • In the beginning, select cell B5 to type this formula.
=DATE(2021,SEQUENCE(12),1)

Combine DATE & SEQUENCE Functions to Increment Month

  • Following hit Enter and you will get the series of incremental dates in the cell range B5:B16.

In this case, insert the target year 2021 in the 1st argument and the day as 1 in the 3rd argument. In the 2nd argument, the SEQUENCE function will return the sequential numbers from 1 to 12. Based on these parameters, the DATE function will produce a series of dates.
  • Now, apply the same formula in the cell range C5:C16.
  • Then, right-click on it and select Format Cells from the Context Menu.

  • Next, go to the Custom section from the Number tab.

  • Here, insert the Type as mmmm and press OK.

  • First, insert your required Start Date in cell C4.

Combine EDATE & SEQUENCE Functions for Incrementing

  • Then, insert this formula in cell B7.
=EDATE(C4, SEQUENCE(12, 1, 0))

  • Lastly, hit Enter.
  • That’s it, you will get the sequential dates all at once.

Here, The EDATE function returns a date along with a month before or after the start date in cell C4. Then, the SEQUENCE function creates an array of 12 numbers as we want to output for 12 months. Following, we typed 1 as the 2nd argument for one-month increments. Also, the start argument is set to 0 and included in the formula.

Things to Remember

  • Make sure all the dates are in the same format after incrementing them by 1. Otherwise, if you get any numeric value after applying any of the above methods, simply change the format from the Format Cells section.
