Formula (Date calculation)

[mahmed1]

Hi Guys,

I need a formula that will calculate how many periods there are up to 01/04

e.g

There are 5 total period between the dates 01.01.2006 and 01.03.2011

Formula in E3 & F3 autofilled down.

Hopefully barry will have a cleaner solution later.

Thank You

I'm Sure Barry or anyone of the genius excel users on this forum will come up with a cleaner solution

Thank You

Hi with this formula there mis a slight change that will need to be

i.e if i use the formulas above

and say a customer moved in on 31/03/2006 and moved back out on 02/04/2006
the formula above will give

<TABLE style="WIDTH: 112pt; BORDER-COLLAPSE: collapse" border=0 cellSpacing=0 cellPadding=0 width=150><COLGROUP><COL style="WIDTH: 56pt; mso-width-source: userset; mso-width-alt: 2742" span=2 width=75><TBODY><TR style="HEIGHT: 15pt" height=20><TD style="BORDER-BOTTOM: #f0f0f0; BORDER-LEFT: #f0f0f0; BACKGROUND-COLOR: transparent; WIDTH: 56pt; HEIGHT: 15pt; BORDER-TOP: #f0f0f0; BORDER-RIGHT: #f0f0f0" class=xl63 height=20 width=75 align=right>31/03/2006 </TD><TD style="BORDER-BOTTOM: #f0f0f0; BORDER-LEFT: #f0f0f0; BACKGROUND-COLOR: transparent; WIDTH: 56pt; BORDER-TOP: #f0f0f0; BORDER-RIGHT: #f0f0f0" class=xl63 width=75 align=right>02/04/2006</TD></TR><TR style="HEIGHT: 15pt" height=20><TD style="BORDER-BOTTOM: #f0f0f0; BORDER-LEFT: #f0f0f0; BACKGROUND-COLOR: transparent; HEIGHT: 15pt; BORDER-TOP: #f0f0f0; BORDER-RIGHT: #f0f0f0" class=xl63 height=20 align=right>01/04/2007</TD><TD style="BORDER-BOTTOM: #f0f0f0; BORDER-LEFT: #f0f0f0; BACKGROUND-COLOR: transparent; BORDER-TOP: #f0f0f0; BORDER-RIGHT: #f0f0f0" class=xl63 align=right>02/04/2006</TD></TR></TBODY></TABLE>

It should be

31/03/06 - 31/03/2006
01/04/2006 - 02/04/2006

Hope this makes sense

Many Thanks

According to your earlier posts, 01/01/2006 to 31/03/2007 was 1 period, however, there are instances where this method will fail that I had previously overlooked.

Maybe
