toOperators & Functions Available
This section explains operators and functions available for formulas for Automatic Calculation.
Operator/Function  Description  Example Formula  

Expression  Calculated Result  
+  Adds numbers.  3+2  5 
  Subtracts numbers. The operator can also be used as unary operator for converting field values to plus or minus. 
32  1 
*  Multiplies numbers.  3*2  6 
/  Divides numbers.  3/2  1.5 
^  Raises a number to a power. From the minus power of 100 to the power of 100 can be calculated. When a decimal is specified for the exponential power, the decimal number is rounded down to the integer. Example: 3^2.5 is converted to 3^2 and the result is 9. 
3^2  9 
&  Concatenates strings.  John & Doe  JohnDoe 
SUM 
Adds numbers. The following format is to be used: 
SUM(1, 2, 3)  6 
DATE_FORMAT 
Change the date and time format and the time zone.

DATE_FORMAT(Date and time, "YYYYMd", "system")  201641 
Please note:
 Operators are applied in the following priority order:
 ^ (Exponentiation)
 */ (Multiplication and division)
 + (Addition and subtraction)
 & (String operator)
Calculating Numbers
 Available arithmetic functions:
 Addition (+)
 Subtraction ()
 Multiplication (*)
 Division (/)
 Exponentiation (^)
 To add numbers in two fields whose field codes are "NumA" and "NumB", formula is NumA + NumB
 To subtract 1000 from the number in the field whose field code is "NumA", and multiply the result by 2, formula is (NumA  1000) * 2
 To cube the number in the field whose field code is "NumA", formula is NumA^3
Representing Positive or Negative Numbers
Use unary arithmetic operators "+" or "" to represent positive values or negative values. Available fields: Calculated, Text.
 To represent the negative number in the field whose field code is "NumA", formula is NumA. When the number in the field whose field code is "NumA" is "100", the result is "100".
 The following calculation can be performed:
 Calculate the number of days, hours, and minutes between two dates and times.
 Add to or subtract from a date and time.
 To calculate the difference between two date and time fields whose field codes are "DatetimeA" and "DatetimeB" respectively, formula is DatetimeA  DatetimeB
 To add one hour to the value of a Time or Number field whose field code is "TimeA", formula is TimeA + (1 * 60 * 60)
Use the string operator "&" to combine text strings. The values in number, date, and time fields can be combined as texts. Available field: Text.
 To combine text from two fields whose field codes are "TextA" and "TextB" into one field, formula is TextA & TextB. When the value in "TextA" is "John" and "TextB" is "Smith", the result is displayed as "JohnSmith".
 To enter a text string in between fields whose field codes are "TextA" and "TextB", enclose it in double quotation marks ("), formula is TextA & " " & TextB. When the value in "TextA" is "John" and "TextB" is "Smith", the result is displayed as "John Smith".
 To sum up values in a column of a table (in the example below, the "Approximate Hours" subtotal), whose field code is "NumA", the formula is SUM(NumA).
 Note: The subtotal column Field type (ie: "Approximate Hours") must be either Calculated or Number.
 The DATE_FORMAT function is used in the following format:
 DATE_FORMAT(Formula, "Date and time format", "Time zone")
 DATE_FORMAT(UNIX time, "Date and time format", "Time zone")
Parameter  Description 
Formula 
For formula, the following fields can be used:
Specify a field with a field code. To add or subtract time to/from date and time, specify time in seconds in the formula. For example, specify "3600" or "60*60*1" for one hour. For one day, specify "24*60*60*1". If the result of the formula is in number, the number is treated as UNIX time. UNIX time is the number of seconds elapsed since 197011 AM 00:00 UTC. It is also called UNIX time stamp. If the date and time is 201641 AM 00:00 (UTC), the UNIX time is "1459468800". 
UNIX time  Specify UNIX time that is less than 10,000,000,000. 
Date and time format  Specify the date and time format of the converted value. For the format, see Date and Time Formats. 
Time Zone  Specify the changed time zone ID or "system". When "system" is specified, the standard time zone set by the administrator is used. The time zone of the field for date and time is fixed at Coordinated Universal Time. To use these fields in formulas, specify the time zone ID "Etc/GMT" of Coordinated Universal Time. When you specify other time zones, you will not obtain the result as you expect. For more information, see Available Time Zones. 
Date & Time Formats
Specify the date and time format by using the format specifiers listed in the following chart. Each format specifier is converted to the corresponding string.
Format  Description  Example (20160401 12:09) 

YYYY  fourdigit year  2016 
MMMM  full name of the month  April 
MMM  threeletter abbreviation of the month  Apr 
MM  twodigit month  04 
M  month without zero padding  4 
dd  twodigit day  01 
d  day without zero padding  1 
a  AM or PM  PM 
KK  hour in the 12 hour clock (0  11)  00 
K  hour in the 12 hour clock (0  11) without zero padding  0 
hh  hour in the 12 hour clock (1  12)  12 
h  hour in the 12 hour clock (1  12) without zero padding  12 
HH  hour in the 24 hour clock (0  23)  12 
H  hour in the 24 hour clock (0  23) without zero padding  12 
kk  hour in the 24 hour clock (1  24)  12 
k  hour in the 24 hour clock (1  24) without zero padding  12 
mm  minute  09 
m  minute without zero padding  9 
ss  second  09 
s  second without zero padding  9 
Z  time zone offset without a colon  +900 
ZZ  time zone offset with two digits  +09:00 
ZZZ  time zone ID  Asia/Tokyo 
 The maximum of 64 characters can be used to specify the date and time format.
 For any format specifier you do not want to be converted, enclose it with single quotation marks (').
 Example of date and time format: D'a'te: d
 Example of the result: Date: 1
 To display a single quotation mark as a string, use two singlequotations in a row.
Example of date and time format: ''
Example of the result: '
 Change the format of Field A to YYYYMd.
 DATE_FORMAT(Field A, "YYYYMd", "system")
 If the value in Field A is "20160401", the calculated result is: 201641.
 Change the time zone of Field A to Pacific Standard Time.
 DATE_FORMAT(Field A, "YYYYMMdd HH:mm", "America/Los_Angeles")
 If the value in Field A is "20160401 13:00", the calculated result is 20160331 21:00.
 Concatenate the string in Field A and the created date and time of the record.
 Field A &"" & DATE_FORMAT(Created datetime, "YYYYMMdd", "system")
 If the value in Field A is "Jane Doe" and the created date and time of the record is "20160410 13:00", the calculated result is: Jane Die20160401.
Automatic Calculation Error List
This section explains the errors displayed in fields where a formula is set.
Error  Description 
#CONVERT!  The value cannot be converted. This error is displayed when the calculated result in the calculated field is a string. The result value in the calculated field should be either number, date and time, date, time or hour. 
#N/A!  The field that is referred by the formula has no entry, or the entered value does not match the type of the calculated field. This error is displayed when a string is entered in the number field. 
#PRECISION!  The result value exceeds the number of significant digits. For details on how to set the significant digits, see the following page: Misc App Settings 
#VALUE!  The calculation cannot be performed or the calculated result is invalid. This error is displayed in the following cases:

#FORMULA!  The DATE_FORMAT function is incorrectly specified in the formula. 
#ERROR!  An unexpected error occurred.

Where can I find a list of available time zone values? "Pacific" is not recognized (as expected), but that doesn't leave me clearer on what values will be recognized.
I'm trying to use this formula in Kintone: DATE_FORMAT(FieldA, "YYYY/MM/dd hh:mm a", "system") and it keeps giving me an error message saying that Date_format function does not exist.
What functions or macros are available for calculation? For example how to express:
(someDate  TODAY())/86400 using only the editor?
Hi Heather,
I have created a Support Ticket on your behalf to discuss the error message.

Hi Tony,
I have created a Support Ticket on your behalf. Please note, calculations that require today's date, such as Age, do require customization.
