Auto comments if dates match

[cpereznj]

Hi everyone, is there a way to add comments based on dates? I have a file with three sheets. The first is called "2018" and is used as a calendar for year 2018 and other data. The second is called "2019" and is used as a calendar for year 2019 and other data. The last one is called "'Events" and it contains a list of special events.
We need to add comments if the dates in the "2018" and "2019" worksheets match date dates in the "Events" worksheet. The comments should be placed in the corresponding "Day" column. The comment should be the event name in column A of the "Events" worksheet.
Thank you for the help.

Hi,

Could you please clarify what you mean? In this case, you'd like cell A4 in the Calendar sheet to indicate something based on cell B3 in the Events sheet?

Michael,

The following is a list of comments and their corresponding cells.
"Events" A3 - Event 1 should be placed in "2018" A3. This is because the date in "2018" B3 matches the date in "Events" B3.
"Events" A4 - Event 2 should be placed in "2018" D3. This is because the date in "2018" E3 matches the date in "Events" B4.
"Events" A5 - Event 3 should be placed in "2018" G3. This is because the date in "2018" H3 matches the date in "Events" B5 and so forth.

Hope this clarifies your question. Thank you for the quick reply.
