No. of days split into periods
Brian, I cannot understand what you are asking. Are the readings from the same meter and you want to work out consumption per calendar month? -- bob777 ------------------------------------------------------------------------ bob777's Profile: http://www.excelforum.com/member.php...o&userid=28504 View this thread: http://www.excelforum.com/showthread...hreadid=506703 |
No. of days split into periods
Hi Brian,
A possible solution might be (cells A!:D4, the dates in first row start in C1): 01/01/2006 01/12/2005 15/01/2006 78 15 31 30/12/2005 300 - 30 14/10/2005 200 - - These cells shown as formulas: 38718 =DATE(YEAR(C1),MONTH(C1)-1,1) 38732 78 =IF($A2=C$1,MIN($A2-C$1+1,$B2),0) =IF($A2=D$1,MIN(MIN(C$1,$A2+1)-D$1,$B2-SUM($C2:C2)),0) 38716 300 =IF($A3=C$1,MIN($A3-C$1+1,$B3),0) =IF($A3=D$1,MIN(MIN(C$1,$A3+1)-D$1,$B3-SUM($C3:C3)),0) 38639 200 =IF($A4=C$1,MIN($A4-C$1+1,$B4),0) =IF($A4=D$1,MIN(MIN(C$1,$A4+1)-D$1,$B4-SUM($C4:C4)),0) Copy column D as far to the right as necessary.
