DAYSBETWEENBASIS(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.

DAYSBETWEENBASIS() calculates the number of days between start date and end date with respect to the count basis factor.

Description

DAYSBETWEENBASIS(SD, ED, basis)

• DAYSBETWEENBASIS() returns the number of days from specified start date to end date.
• $SD$ 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.

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: DAYSBETWEENBASIS(#1/1/2014-2/1/2014,"4/1/2014").
• #date notation needs mm/dd/yy format .
