###### formatDate (date; format; [timezone])

When to use it: You have a Date value that you wish to convert (format) to a Text value (textual human readable representation) like 12-10-2019 20:30 or Aug 18, 2019 10:00 AM

###### Parameters

The second column indicates the expected type. If different type is provided, Type Coercion is applied.

 date Date Date value to be converted to a Text value. format Text Format specified using Tokens for date/time formatting. Example: DD.MM.YYYY HH:mm timezone Text Optional. The timezone used for the conversion. See List of tz database time zones, column "TZ database name" for the list of recognized timezones. If omitted, the Organization's timezone specified in your Profile settings will be applied (tab: Time zone options, section: Scenarios, row: the organization the scenario belongs to). Examples: Europe/Prague, UTC

Only the values listed in the "TZ database name" column are recognized by the function as a valid timezone. Any other value will be ignored and the Organization's timezone specified in your Profile will be used instead.

###### Return value and type

Text representation of the given Date value according to the specified format and timezone. Type is Text.

###### Examples

The Organization's and Web's timezone were both set to Europe/Prague in the following examples.

               formatDate(1. Date created;MM/DD/YYYY)
= 10/01/2018

               formatDate(1. Date created;YYYY-MM-DD hh:mm A)
= 2018-10-01 09:32 AM

               formatDate(1. Date created;DD.MM.YYYY HH:mm;UTC)
= 01.10.2018 07:32

               formatDate(now;DD.MM.YYYY HH:mm)
= 19.03.2019 15:30

###### How to calculate n-th day of week in month

[adapted for Make from this original source]

If you need to calculate a date corresponding to n-th day of week in month (e.g. 1st Tuesday, 3rd Friday, etc.), you may use the following formula:

You may copy and paste the formula's code into a field:

               {{addDays(setDate(1.date; 1); 1.n * 7 - formatDate(addDays(setDate(1.date; 1); "-" + 1.dow); "E"))}}


The formula contains the following items:

 1.n n-th day: 1 for 1st Tuesday 2 for 2nd Tuesday 3 for 3rd Tuesday,etc. 2.dow day of week: 1 for Monday 2 for Tuesday 3 for Wednesday 4 for Thursday 5 for Friday 6 for Saturday 7 for Sunday 1.date The date determines the month. To calculate n-th day of week in current month use the now variable.

In case you wish to calculate only one specific case, e.g. 2nd Wednesday, you may replace the items 1.n and 2.dow in the formula with corresponding numbers. For 2nd Wednesday in current month you would use the following values:

• 1.n = 2

• 1.dow = 3

• 1.date = now

Explanation:

• setDate(now;1) returns first of current month

• formatDate(....;E) returns day of week (1, 2, ... 6)

• see the original source for the rest

###### How to calculate days between dates

One possibility is to employ the following expression:

You can copy & paste the following code:

               {{round((2.value - 1.value) / 1000 / 60 / 60 / 24)}}


NOTE: Values of D1 and D2 have to be of type Date. If they are of type String (e.g. "20.10.2018"), use parseDate() function to convert them to type Date.

INFO: The round() function is used for cases when one of the dates falls within the daylight savings time period and the other not. In these cases, the difference in hours is by one hour less/more and dividing it by 24 gives a non-integer results.

###### How to calculate last day/millisecond of month

When specifying a date range (e.g. in a search module) spanning the whole previous month as closed interval (the interval that includes both its limit points), it is necessary to calculate last day of month.

2019-09-01 ≤ D ≤ 2019-09-30

The formula below shows one way how to calculate last day of the previous month:

You can copy & paste the following code:

               {{addDays(setDate(now; 1); -1)}}


In some cases, it is necessary to calculate not only the last day of month, but literally its last millisecond:

2019-09-01T00:00:00.000Z ≤ D ≤ 2019-09-30T23:59:59.999Z

The formula below shows one way how to calculate last millisecond of the previous month:

You can copy & paste the following code:

               {{parseDate(parseDate(formatDate(now; "YYYYMM01"); "YYYYMMDD"; "UTC") - 1; "x")}}


If the result should respect your timezone settings, simply omit the UTC argument:

               {{parseDate(parseDate(formatDate(now; "YYYYMM01"); "YYYYMMDD") - 1; "x")}}


However, it is preferable to use half-open interval instead (the interval that excludes one of its limit points), specifying the first day of the following month instead and replacing the less or equal than operator with less than:

2019-09-01 ≤ D < 2019-10-01

2019-09-01T00:00:00.000Z ≤ D < 2019-10-01T00:00:00.000Z

###### How to transform seconds into hours, minutes and second

One possibility is to use the following expression shown below:

You can copy & paste the following code:

               {{floor(1.seconds / 3600)}}:{{floor((1.seconds % 3600) / 60)}}:{{((1.seconds % 3600) % 60)}}


NOTE: Values of Second should be number type. This function is suited only if the second value is less than 86400 ( less than a day ).
