The advance formula function is the pre-built function in Salesforce, that we will use to do calculations, work with date, time, and data, and also to convert text.

We can use these formula functions in Salesforce workflow rules, formula fields, process builders, validation rules, etc. The Salesforce advance formula functions include logical, mathematical, text, date, and time functions.

With this, we have learned about Salesforce Advance Formula Function. Now, we will proceed and learn about Salesforce Date Function Formula.

## Salesforce Date Formula Function

As we mentioned above, Salesforce Advance Formula Functions include Date and Time Functions. So, we will now talk about the Salesforce Date Formula Function in detail.

The Date formula function is the type of advance formula function in Salesforce. It is used to work with dates and times.

These functions are used to format dates and times, extract data, calculate gaps between dates, and conduct other actions on dates and times.

This has taught us about the Salesforce Date Formula Function. Now, we’ll continue and learn about Salesforce Date Function Formula applications.

## Applications of Date Formula Functions in Salesforce

Here, are some applications of Salesforce Date Formula Functions:

• The date formula function is used to calculate the age of an account holder.
• We can use the date formula function to calculate how many years your account is old.
• The date functions can be used to arrange follow-up actions for a certain day, such as scheduling a phone call, campaign, task, lead check, etc.
• We can use the date formula function to calculate the number of days between specific date range records.
• The date functions can be used to determine the duration of an event, and also the last date.
• To calculate the expiry date of contracts, licenses, certifications, and products, we use the Salesforce date functions.
• To build custom date and time fields that fit our unique business needs, we utilize the date function formulas.

As a result, we now know some common use cases of Salesforce Date formula functions. Next, weâ€™ll look at various commonly used date formula functions in Salesforce with examples.

## Common used Date Formula Functions in Salesforce

There are a number of date functions available in formula fields in Salesforce. Some of the most popular ones are highlighted below:

• TODAY(): This function is used to return the present date.
• NOW(): This function returns the time and date as of the moment.
• DATE(): This function creates and returns a date that matches the given year, month, and day.
• YEAR(): This function returns the corresponding year.
• MONTH(): This function returns a month as a number for a given date.

• DATETIMEVALU(): This function transforms a DateTime string into a DateTime value.
• ADDMONTHS(): This function extends a date by a predetermined number of months.

Let’s discuss each of these functions in detail with syntax and examples.

### Salesforce TODAY() function

TODAY() formula function in Salesforce, is used to return the current date only without any time value. It returns the date based on the user’s time zone setting in Salesforce.

The syntax of the function is as given below:

``TODAY()``
• This function does not include any parameter, we only have to write the word TODAY in the formula.

Let’s see a simple example, of where we can use the TODAY function.

Suppose, we want to calculate the number of days between the current date and the birth date of the employee. So, for this, we will use the TODAY() function in the formula field.

Here, is the formula:

``TODAY() - Birthday__c``
• In this example, we subtract the TODAY() function from the Birth Date custom date field called “Birthday__c”, which returns the number of days between the current date and the birthdate.
• This advance formula function, return result in a numeric value representing the number of days.

If we want to return the date value with time information, we need to use the NOW() function. So, let’s proceed and learn about the NOW function in detail.

### Salesforce NOW() function

Here, is the formula:

``IF(Expiry_Date_Time__c > NOW(), Expiry_Date_Time__c - NOW(), 0)``
• In this example, we will use the IF function, which checks whether the custom field expiry date and time called “Expiry_Date_Time__c” is greater than the current date and time called “NOW()”.
• If it is, the formula subtracts the current date and time from the expiry date and time and returns the time left until the due date and time.
• If not, the formula returns 0.

If we want to return and store the date value, we need to use the DATE() function. So, let’s proceed and learn about the DATE function in detail.

### Salesforce DATE() function
