Manipulating date and time with the datecalc function

The datecalc function accepts one or two parameters, as follows:

$time_datecalc([dateTime,] offset_expression)

dateTime

If date and time are not specified, the current date and time are assumed. This parameter is optional. The supported format is yyyy-mm-dd.

offset_expression

The expression represents one or more operations to be applied to date and time. This parameter is required. You can build an offset expression by combining one or more of the following parameters:

+ offset_number token

adds the specified token by the specified offset_number.

- offset_number token

subtracts the specified token by the specified offset_number.

nearest token

changes the date and time to the nearest token.

next token

changes the date and time to the next token.

previous token

changes the date and time to the previous token.

where:

offset_number

The number to be applied to the token.

A token can indicate a day, an amount of time, or a calendar name, as listed below. To indicate a quantity higher than 1, add the "s" at the end of the token:

minute("s")

The unit of measure to be used in the expression is one or more minutes.

hour("s")

The unit of measure to be used in the expression is one or more hours.

day("s")

The unit of measure to be used in the expression is one or more days, regardless of whether the day is working or non-working.

weekday("s")

The unit of measure to be used in the expression is one or more days of the week, except Saturday and Sunday.

workday("s")

The unit of measure to be used in the expression is one or more working days, that is every day of the week except Saturday and Sunday, unless otherwise specified in a non-working days calendar defined for the workflow. You can use the non-working days calendar to manage non-working days which vary over time.

week("s")

The unit of measure to be used in the expression is one or more weeks.

month("s")

The unit of measure to be used in the expression is one or more months.

year("s")

The unit of measure to be used in the expression is one or more years.

To indicate weekdays and workdays, use one of the following notations:

mo, mon, monday

Use the following expression to add one day to the current date (2022-04-01):

$time_datecalc('+1 day')

The result is similar to the following:

2022-04-02T16:30:00+02:00[Europe/Rome]

Use the following expression to calculate the last day of the month starting from 2022-04-01:

$time_datecalc('2022-04-01','next monthend')

The result is similar to the following:

2022-04-30T16:30:10.123+02:00[Europe/Rome]

Use the following expression to calculate the next Monday starting from today (2022-04-01) and add one day to the result:

$time_datecalc('+ nearest mo +1 day')

The result is similar to the following:

2022-04-05T00:00:00+02:00[Europe/Rome]

Use the following expression to add 30 working days to 2022-04-01:

$time_datecalc('2022-04-01T16:30:00','+30 workdays')

The result is similar to the following:

2022-05-13T16:30:00+02:00[Europe/Rome]

Use the following expression to calculate the last day of the month starting from 2022-04-01 and express it in the local date:

$time_datecalc('next monthend').$time_localDate()

The result is similar to the following:

4/30/2022
