# Date formulas
Video guide: Learn how to transform dates with formula mode
Workato supports a variety of date and datetime formulas.
Formulas in Workato are allowlisted Ruby methods. Syntax and functionality for these formulas are generally unchanged. Most formulas return an error and stop the job if the formula operates on nulls (expressed as nil in Ruby), except for present?, presence, and blank?.
You can refer to the Ruby documentation on time (opens new window) for more information. However, only allowlisted Ruby methods are supported. To request the addition of new formulas to the allowlist, submit a support ticket (opens new window).
# Date arithmetic
Use the following keywords to perform arithmetic with date and datetime data:
secondsminutesdaysmonthsyears
When combined with a formula, you can perform addition and subtraction.
# Sample usage
| Date Arithmetic | Output |
|---|---|
| "2020-01-01".to_date + 2.days | "2020-01-03" |
| "2020-01-01".to_date - 2.days | "2019-12-30" |

# to_date
This formula converts input data into a date and returns the date formatted as YYYY-MM-DD.
# Syntax
String.to_date(format: format)
- String - A string input that describes a date or datetime.
- format - (optional) The format of the input date string. If not specified, Workato parses the input string automatically.
FORMAT PARAMETER DOESN'T AFFECT OUTPUT FORMAT
The format parameter defines only the input format. It does not affect the output format, which is always returned as YYYY-MM-DD.
# Sample usage
| Formula | Result |
|---|---|
| "23-01-2020 10:30 pm".to_date(format: "DD-MM-YYYY") | "2020-01-23" |
| "01-23-2020 10:30 pm".to_date(format: "MM-DD-YYYY") | "2020-01-23" |
| "2020/01/23".to_date(format: "YYYY/MM/DD") | "2020-01-23" |
| "06/27/25".to_date(format: "%m/%d/%y") | "2025-06-27" |
# How it works
Converts the input data into a date datatype.
INPUT DATA BEST PRACTICE
We recommend that you specify the input data format. If you don't specify the input data format, Workato parses the input string automatically.
The input string must resemble a date for this formula to work.
# See also
# to_time
Converts a string to an ISO timestamp. The response will use the UTC timezone (+00:00).
# Syntax
String.to_time(format: format)
- String - An input string that describes a date or datetime.
- format - (optional) The format of the user-defined datetime written as a string.
# Sample usage
| Formula | Result |
|---|---|
| "2020-04-02T12:30:30.462659-07:00".to_time(format: "%Y-%m-%dT%H:%M:%S") | "2020-04-02T19:30:30.000+00:00" |
| "2020-04-02".to_time | "2020-04-02T00:00:00.000+00:00" |
# How it works
Converts the input string into a datetime datatype. The output datetime will be converted to the UTC timezone (+00:00).

If the input data does not include the time, the output will default to 00:00:00.000000 +00:00.

- strftime: Returns datetime is a custom format.
- to_date: This formula converts the date-like input into a date. Returns the date formatted as YYYY-MM-DD.
# Parameters
As previously shown, each code (%B, %e, %I, for example) refers to a specific element of datetime. You can also add static text and punctuation, such as commas (,), slashes (/), and colons (:). Refer to the following list of frequently used codes:

| %e | Day of the month without zero-prefix | 5 |
| %H | Hour of the day (24-hour) | 17 |
| %k | Hour of day without 0 prefix (24-hour) | 17 |
| %I (capital i) | Hour of the day (12-hour) | 05 |
| %l (lowercase L) | Hour of day without 0 prefix (12-hour) | 5 |
| %p | AM or PM | PM |
| %M | Minute of the hour | 13 |
| %S | Second of the minute | 27 |
| %L | Millisecond of the second | 000 |
| %z | Time zone offset from UTC | -0700 |

# to_i
Convert datetime into epoch time. Returns an epoch time in UTC (+00:00).

- Datetime - An input datetime.
# Sample usage
| Formula | Result |
|---|---|
| today.to_time.to_i | 1645660800 |
| now.to_i | 1645714000 |
# How it works
Converts the input datetime into an integer, it will return epoch time in seconds, not milliseconds. The output datetime will be converted to the UTC timezone (+00:00).
Converting between Epoch time to datetime
Convert time formats easily with Workato formulas.
# How to convert human readable time to epoch time
Use to_i to convert a datetime datapill to epoch time (in UTC). Learn more about how it works.
# How to convert epoch time to human-readable time
Use the following formula to convert an epoch time to human-readable datetime.
Note that the output will be in UTC timezone (+00:00).
"1970-01-01".to_time +Epoch time.seconds
If you plan to convert epoch time to a specific timezone, you must specify it with in_time_zone.
"1970-01-01".to_time.in_time_zone("US/Pacific") +Epoch time.seconds
Wrong datatype: undefined method `to_i`
Epoch time requires a datetime datapill. If you are using a date datapill, it will cause an error.
Use to_time to convert a date into a datetime before converting to epoch time.
