Counting # of Days Since Last Occurrence

[dconley]

Hey Everyone,

I'm fairly new at building spreadsheets. I'm trying to be able to write a function that will look at one column of attendees, and tell me the number of days since the same number of attendees occurred. For example, the table below:

<TABLE style="WIDTH: 126pt; BORDER-COLLAPSE: collapse" border=0 cellSpacing=0 cellPadding=0 width=168 x:str><COLGROUP><COL style="WIDTH: 41pt; mso-width-source: userset; mso-width-alt: 2011" width=55><COL style="WIDTH: 44pt;

It's easy to see that on Day 10, the number of days since 5 people showed up is 6. When this is over the course of a year, it's more difficult. I would like a separate table like below showing the calculations:

I've been able to show the number of occurrences, using a countif formula, and also a rank table. I would just like some guidance on getting the above accomplished, and any help is greatly appreciated.

Welcome to the Board,

When you say..."the number of days since the same number of attendees occurred.",
from which day is that measured?

Is the measure:
1. The last day logged on your first table minus the last day each number of attendees occurred; or
2. The last day last day each number of attendees occurred minus the next previous time that number of attendees occurred?

The second table doesn't exactly match either of those definitions.

It's easy to see that on Day 10, the number of days since 5 people showed up is 6. When this is over the course of a year, it's more difficult. I would like a separate table like below showing the calculations:

<table style="WIDTH: 106pt; BORDER-COLLAPSE: collapse" x:str="" border="0" cellpadding="0" cellspacing="0" width="141"><colgroup><col style="WIDTH: 51pt; mso-width-source: userset; mso-width-alt: 2486" width="68"><col style="WIDTH: 55pt; mso-width-source: userset; mso-width-alt: 2669" width="73"></colgroup><tbody><tr style="HEIGHT: 12.75pt" height="17"><td style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; WIDTH: 51pt; HEIGHT: 12.75pt; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" class="xl65" height="17" width="68"># ATTEND</td><td style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; WIDTH: 55pt; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" class="xl65" width="73">Days Since</td></tr><tr style="HEIGHT: 12.75pt" height="17"><td style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; HEIGHT: 12.75pt; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" class="xl65" x:num="" height="17">0</td><td style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" class="xl65" x:num="">10</td></tr><tr style="HEIGHT: 12.75pt" height="17"><td style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; HEIGHT: 12.75pt; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" class="xl65" x:num="" height="17">1</td><td style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" class="xl65" x:num="">10</td></tr><tr style="HEIGHT: 12.75pt" height="17"><td style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; HEIGHT: 12.75pt; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" class="xl65" x:num="" height="17">2</td><td style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" class="xl65" x:num="">10</td></tr><tr style="HEIGHT: 12.75pt" height="17"><td style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; HEIGHT: 12.75pt; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" class="xl65" x:num="" height="17">3</td><td style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" class="xl65" x:num="">4</td></tr><tr style="HEIGHT: 12.75pt" height="17"><td style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; HEIGHT: 12.75pt; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" class="xl65" x:num="" height="17">4</td><td style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" class="xl65" x:num="">2</td></tr><tr style="HEIGHT: 12.75pt" height="17"><td style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; HEIGHT: 12.75pt; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" class="xl65" x:num="" height="17">5</td><td style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" class="xl65" x:num="">0</td></tr><tr style="HEIGHT: 12.75pt" height="17"><td style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; HEIGHT: 12.75pt; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" class="xl65" x:num="" height="17">6</td><td style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" class="xl65" x:num="">8</td></tr><tr style="HEIGHT: 12.75pt" height="17"><td style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; HEIGHT: 12.75pt; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" class="xl65" x:num="" height="17">7</td><td style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" class="xl65" x:num="">10</td></tr><tr style="HEIGHT: 12.75pt" height="17"><td style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; HEIGHT: 12.75pt; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" class="xl65" x:num="" height="17">8</td><td style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" class="xl65" x:num="">7</td></tr><tr style="HEIGHT: 12.75pt" height="17"><td style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; HEIGHT: 12.75pt; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" class="xl65" x:num="" height="17">9</td><td style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" class="xl65" x:num="">5</td></tr></tbody></table>

Your narrative indicates it has been 6 days since 5 people attended - which is correct based on the first table; however, the second table shows it has been zero days since 5 people attended.

Please clarify what you are seeking and include the formula you used...
