Recurring tasks using Gantt Charts and Conditional Formatting

[MarisaRaucci]

Hi,
I am trying to come up with a formula to calculate biweekly dates in excel, using conditional formatting. Ideally I would like to be able to enter the start date and end date, day of week, and frequency, and identify the dates using an X, then a conditional format to shade the X using a specific colour. For example:

					Mon 1 October	Tue 2 Oct
	Day of Week	Frequency	Project Start Date	Project End Date
Status Meeting	Tue	bi weekly	1 October 2021	1 November 2021		X

I would like to be able to set up a formula in in the above table to be able to capture when the biweekly meetings occur, and then place an X in the date it relates to. I am using Excel, and don't have access to Project Management, but I am quite sure that someone can come up with this formula.

thanks
Marisa

you are welcome, glad to have helped

The file will only be on the share for a few days , and then removed , hence why i also included the XL2BB for anyone searching in the future will still be able to see the solution, even without the workbook

Hi again, one question I forgot to ask, if I wanted to choose distinguish from the bi weekly and weekly meetings with a different colour, can this be done? I have used conditional formatting so that if there is an X, it use red, but now I'm thinking it would be great if I could use two different colours to do this.

Can this be achieved?

cheers
Marisa

you can do a few things we could change the X to a different value
BUT keeping the X
then we would add 2 rules to conditional formatting
one would check for an X and Bi Weekly - say format RED
and 2nd rule for an X and Weekly - say format Green

Rule 1 = =AND( $E2="Bi Weekly", H2="X") for Bi Weekly and format Green
Rule 2 = =AND($E2="weekly", H2="X") for Weekly and format Green
