-# DATEVALUE
+# DATEVALUE function

-::: warning
-🚧 This function is implemented but currently lacks detailed documentation. For guidance, you may refer to the equivalent functionality in [Microsoft Excel documentation](https://support.microsoft.com/en-us/office/excel-functions-by-category-5f91f4e9-7b42-46d2-9bd1-63f26a86c0eb).
-:::
+## Overview
+DATEVALUE is a function of the Date and Time category that converts a date stored as text to a [serial number](/features/serial-numbers.md) corresponding to a date value.
+
+## Usage
+### Syntax
+**DATEVALUE(<span title="Text" style="color:#1E88E5">date_text</span>) => <span title="Number" style="color:#1E88E5">datevalue</span>**
+
+### Argument descriptions
+* *date_text* ([text](/features/value-types#strings), required). A text string that represents a date in a known format. The text must represent a date between December 31, 1899 and December 31, 9999.
+
+### Additional guidance
+* If the year portion of the *date_text* argument is omitted, DATEVALUE uses the current year from the system clock.
+* Time information in the *date_text* argument is ignored. DATEVALUE processes only the date portion.
+
+### Returned value
+DATEVALUE returns a [number](/features/value-types#numbers) that represents the date as a [serial number](/features/serial-numbers.md). The serial number corresponds to the number of days since December 31, 1899.
+
+### Error conditions
+* In common with many other IronCalc functions, DATEVALUE propagates errors that are found in its argument.
+* If no argument, or more than one argument, is supplied, then DATEVALUE returns the [`#ERROR!`](/features/error-types.md#error) error.
+* If the value of the *date_text* argument is not (or cannot be converted to) a [text](/features/value-types#strings) value, then DATEVALUE returns the [`#VALUE!`](/features/error-types.md#value) error.
+* If the *date_text* argument represents a date outside the valid range (before December 31, 1899 or after December 31, 9999), then DATEVALUE returns the [`#VALUE!`](/features/error-types.md#value) error.
+* If the *date_text* argument cannot be recognized as a valid date format, then DATEVALUE returns the [`#VALUE!`](/features/error-types.md#value) error.
+<!--@include: ../markdown-snippets/error-type-details.txt-->
+
+<!-- ## Details
+For more information on how IronCalc processes Date and Time functions and values, visit [Date and Time](/features/serial-numbers.md) 
+
+## Examples
+[See some examples in IronCalc](https://app.ironcalc.com/?example=datevalue).
+-->
+
+## Links
+* See also IronCalc's [TIMEVALUE](/functions/date_and_time/timevalue.md) function for converting time text to serial numbers.
+* Visit Microsoft Excel's [DATEVALUE function](https://support.microsoft.com/en-us/office/datevalue-function-df8b07d4-7761-4a93-bc33-b7471bbff252) page.
+* Both [Google Sheets](https://support.google.com/docs/answer/3093039) and [LibreOffice Calc](https://wiki.documentfoundation.org/Documentation/Calc_Functions/DATEVALUE) provide versions of the DATEVALUE function.

-# TIMEVALUE
+# TIMEVALUE function

-::: warning
-**Note:** This draft page is under construction 🚧
-The TIMEVALUE function is implemented and available in IronCalc.
-:::
+## Overview
+TIMEVALUE is a function of the Date and Time category that converts a time stored as text to a [serial number](/features/serial-numbers.md) corresponding to a time value. The serial number represents time as a decimal fraction of a 24-hour day (e.g., 0.5 represents 12:00:00 noon).
+
+## Usage
+### Syntax
+**TIMEVALUE(<span title="Text" style="color:#1E88E5">time_text</span>) => <span title="Number" style="color:#1E88E5">timevalue</span>**
+
+### Argument descriptions
+* *time_text* ([text](/features/value-types#strings), required). A text string that represents a time in a known format. The text must represent a time between 00:00:00 and 23:59:59.
+
+### Additional guidance
+* Date information in the *time_text* argument is ignored. TIMEVALUE processes only the time portion.
+* The function can handle various time formats, including both 12-hour and 24-hour formats, as well as text that includes both date and time information.
+
+### Returned value
+TIMEVALUE returns a [number](/features/value-types#numbers) that represents the time as a [serial number](/features/serial-numbers.md). The serial number is a decimal fraction of a 24-hour day, where:
+* 0.0 represents 00:00:00 (midnight)
+* 0.5 represents 12:00:00 (midday)
+* 0.99999... represents 23:59:59 (just before midnight)
+
+### Error conditions
+* In common with many other IronCalc functions, TIMEVALUE propagates errors that are found in its argument.
+* If no argument, or more than one argument, is supplied, then TIMEVALUE returns the [`#ERROR!`](/features/error-types.md#error) error.
+* If the value of the *time_text* argument is not (or cannot be converted to) a [text](/features/value-types#strings) value, then TIMEVALUE returns the [`#VALUE!`](/features/error-types.md#value) error.
+* If the *time_text* argument represents a time outside the valid range, then TIMEVALUE returns the [`#VALUE!`](/features/error-types.md#value) error.
+* If the *time_text* argument cannot be recognized as a valid time format, then TIMEVALUE returns the [`#VALUE!`](/features/error-types.md#value) error.

+# DEGREES function

-::: warning
-🚧 This function is not yet available in IronCalc.
-[Follow development here](https://github.com/ironcalc/IronCalc/labels/Functions)
-:::
+## Overview
+DEGREES is a function of the Math and Trigonometry category that converts an angle measured in radians to an equivalent angle measured in degrees.
+
+## Usage
+### Syntax
+**DEGREES(<span title="Number" style="color:#1E88E5">angle</span>) => <span title="Number" style="color:#1E88E5">degrees</span>**
+
+### Argument descriptions
+* *angle* ([number](/features/value-types#numbers), required). The angle in radians that is to be converted to degrees.
+
+### Additional guidance
+The conversion from radians to degrees is based on the relationship:
+$$
+1~\:~\text{radian} = \dfrac{180}{\pi}~\text{degrees} \approx 57.29577951~\text{degrees}
+$$
+
+### Returned value
+DEGREES returns a [number](/features/value-types#numbers) that represents the value of the given angle expressed in degrees.
+
+### Error conditions
+* In common with many other IronCalc functions, DEGREES propagates errors that are found in its argument.
+* If no argument, or more than one argument, is supplied, then DEGREES returns the [`#ERROR!`](/features/error-types.md#error) error.
+* If the value of the *angle* argument is not (or cannot be converted to) a [number](/features/value-types#numbers), then DEGREES returns the [`#VALUE!`](/features/error-types.md#value) error.

+EVEN is a function of the Math and Trigonometry category that rounds a number up (away from zero) to the nearest even integer.

+## Usage
+### Syntax

+* EVEN rounds away from zero, meaning:
+  * Positive numbers are rounded up to the next even integer.
+  * Negative numbers are rounded down (toward negative infinity) to the next even integer.
+* If the *number* argument is already an even integer, EVEN returns it unchanged.
+* Since zero is considered an even number, the EVEN function returns 0 when *number* is 0.
