YEARFRAC(SD, ED, basis)

where

• $SD$ represents a start date,
• $ED$ represents an end date, and
• $basis$ is the type of day count basis to use.

YEARFRAC() calculates the fraction of the year depending on the number of days between start date and end date.

Description

YEARFRAC(SD, ED, basis)

• YEARFRAC() returns the fractional proportion of the year from specified start and end dates.
• $SD$ and $ED$ dates should be entered either in 'date format' or 'dates returned using formulas'. If dates are not valid, Calci displays #N/A error message.
• $SD$ date should be < $ED$, else Calci displays NaN error message.
• $basis$ value is optional. If omitted, Calci assumes it to be 0.
• We can use the DD/MM/YYYY format also. For Example:"14/5/2005[DD/MM/YYYY]".

Below table shows the use of $basis$ values:

Basis	Description
0	US (NASD) 30/360
1	Actual/actual
2	Actual/360
3	Actual/365
4	European 30/360

• If $basis$ value is other than 0 to 4, Calci displays #N/A error message.
• We can use range values also.For Example :YEARFRAC(DATE(2014,1,1),#4/1/2015-4/1/2020)

Examples

YEARFRAC(SD, ED, basis) function with inputs in order is calculated as follows:

1/4/2008
10/10/2008
4

=YEARFRAC(A1,A2,A3) : Calculates the fraction Value of the year with the inputs 
in the range A1 to A3. Returns 0.7666666666666667 as a result.
=YEARFRAC(DATE(2014,1,1),DATE(2014,4,1)) : Calculates the fraction Value of the year 
within the dates mentioned. Returns 0.25 as a result.
=YEARFRAC(DATE(2014,1,1),DATE(2015,4,1)) : Calculates the fraction Value of the year 
within the dates mentioned. Returns 1.25 as a result.
=YEARFRAC("1/1/2014[DD/MM/YYYY]","14/4/2015[DD/MM/YYYY]") = 1.2861111111111112
