YEARFRAC (From,To,Basis)

where

• $From$ represents a start date,
• $To$ 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(From,To,Basis)

• YEARFRAC() returns the fractional proportion of the year from specified start and end dates.
• $From$ and $To$ dates should be entered either in 'date format' or 'dates returned using formulas'. If dates are not valid, Calci displays #N/A error message.
• $From$ date should be < $To$, 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 (From,To,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
