Summary
Using Time Functions in Excel
Calculating Dates and using the Function Library
Calculating Number of Days
• Function
– Uses WORDS
– Uses numbers and cell references
Working with Dates
• TODAY() - function returns today's date based on
your system clock and does not include the time.
• NOW() - function returns today's date and includes
the time.
• NETWORKDAYS - counts the number of business days
between the dates given
Holidays must be stated as dates to work as an
exception
Calculate Future Dates
• To find the number of days between now and a date
in the future we use this formula
=“mm/dd/yy”-NOW()
=“10/06/17”-NOW()
Format the cell that contains the answer as a number!

“Video Sample Data” (XL File)
Using COUNTIFS and SUMIFS
• COUNTIFS - applies criteria to cells across multiple
ranges and counts the number of times all criteria
are met.
• SUMIFS - adds the cells in a range that meet multiple
criteria
• Understanding CountIfs and SumIfs (Video: 5:31)
COUNTIFS
• COUNTIFS – (the S allows MORE THAN 1 criteria and
range) up to 127 range/criteria pairs
• Function: Count cells that match multiple criteria
• Result: The number of times criteria are met in
the data
Looks like: =COUNTIFS(range1, criteria1, [range2],
[criteria2],…)
Range1 – the first range to evaluate
Criteria1 – the criteria to use on range1
Range2 – the second range to evaluate

COUNTIFS
• COUNTIFS(criteria_range1, criteria1, [criteria_range2,
criteria2]…)
• The COUNTIFS function syntax has the following arguments:
• criteria_range1 Required. The first range in which to
evaluate the associated criteria.
• criteria1 Required. The criteria in the form of a number,
expression, cell reference, or text that define which cells will
be counted. For example, criteria can be stated as 32, ">32",
B4, "apples", or "32".
• criteria_range2, criteria2, ... Optional. Additional ranges and
their associated criteria. Up to 127 range/criteria pairs are
allowed.
• IMPORTANT: Each additional range must have the same
number of rows and columns asthe criteria_range1 argument.
The ranges do not have to be next to each other.
