Prevent and remove arterial plaque naturally. (Health Secrets) The arteries are major blood vessels the heart uses to pump blood from it to the rest of the body. Over time, arterial walls can become congested with a fatty substance known as plaque. When this happens to a severe point, the arteries may begin to harden and the blood flow can become compromised and ultimately result in a heart attack. Mainstream medicineâs approach for treating plaque is to use drugs or surgery.
Adding Dates You can add some number of days to a date by simply using the =SUM function. Since Excel stores dates as a number of days, no further work is required. For example, to add 5 days to 1/1/98, in A1, use =A1+5, which gives 1/6/98.To add a number of months or years to a date, you first need to decompose the initial date into its year, month, and day components, add in the desired offset, and then have Excel put the components back together.For example, say you have a date in A1, to which you want to add 3 months and 4 days.or example, adding 6 months and 10 days to 8/25/97, in A1 with the formula. =DATE(YEAR(A1),MONTH(A1)+6, DAY(A1)+10). Generally, you cannot add two dates that are in serial format. For example, adding 1/15/1998 and 6/15/1998 gives 6/30/2096, which is essentially meaningless.
So for dates before 03/01/1900, the Excel number is effectively the number of days after 12/31/1899. However, Excel will not format any number below 0 (-1 gives you ##########) and so this only matters for 01/00/1900 to 02/28/1900, making it easier to just use the 12/30/1899 date as a base.f you change the format of the cells to General then this will show the date value of a cell as behind the scenes Excel saves a date as the number of days since 01/01/1900. If your date is text and you need to convert it then DATEVALUE will do this: share | improve this answer. answered Nov 1 '13 at 8:05.
