=====Spreadsheet=====
====Replace dates with incremented year====
Your spreadsheet has a column with dates, starting with say A4 with 1/2/2019 and you want to replace the dates in the this and the rest of the column with the next year, e.g., 2020.  
  - Insert new (temporary) column to right of dates column (it's a new and blank column B)
  - Apply this here formula in new column B next to the first date you want to change.  Say column A row 4 has 1/2/2019.  Put this formula in column B row 4: <code>=DATE(year(A4)+1,month(A4),day(A4))</code>
  - Select the cell B4 and drag down to select all rows in column B that you want to use to replace column A's dates
  - Control-D (pastes the formula down the column). You should see the updated dates in this new column B. 
  - Select all of the column B cells you have changed, and copy to clipboard
  - Put cursor in first date you want to change, that is, in cell A4
  - Edit > Paste Special > Paste Special.  Make sure ''Paste all'' is **not** checked and ''Formula'' is **not** checked.  Paste.  OK the overwrite. 
  - You can now safely delete this column B.

====Give a Cell a Name and Use It Elsewhere====
It's easier to name a cell so that (a) references make sense and (b) you can move the cell but retain the reference.\\ //for example referencing payment totals when adding/deleting rows/columns around them.//

How to name a cell
  * Select the cell
  * Upper-left corner, see the letter-number (e.g., D23) of the cell. Type the name you want in this spot (e.g., CCjan)
  * Repeat as needed
Alternatively you can select the cell, Sheet > Named Ranges and Expressions > Define 

How to use a named cell
  * Select the cell to reference the name
  * Type = and start to type the cell name (e.g, C C j a)
  * When the desired name is the only choice, press enter.

Note that names can be used within formulas.
