COUPDAYS(settlement, maturity, frequency, basis)

Where $settlement$ is the security's settlement date (a date when coupon or a bond is purchased),
$maturity$ is the security's maturity date (a date when coupon or a bond expires),
$frequency$ is the number of coupon payments per year, and
$basis$ is the type of day count basis to use.

COUPDAYS() calculates the number of days in the coupon period.

COUPDAYS() calculates the number of days between the coupon dates surrounding the settlement date.
$settlement$ and $maturity$ dates should be entered either in 'date format' or 'dates returned using formulas'. If dates are not valid, Calci displays #N/A error message.
If $settlement$ date ≥ $maturity$ date, Calci displays #N/A error message.
The values for $frequency$ should be 1,2 or 4.

For Annual payment, frequency = 1,

For Semi-annual payment, frequency = 2,

For Quarterly payment, frequency = 4.

Below table shows the use of $basis$ values:

Consider the following example that shows the use of COUPDAYS function:

=COUPDAYS(A1,A2,A3,A4) displays 183 as a result.
=COUPDAYS(DATE(2012,1,1),DATE(2013,1,1),1,1) displays 366 as a result.
