# Parse a date or time Shape / columns parse, format or decompose dates and times; date arithmetic; time zones Page: ## Status Runs as a SQL step. arcform carries it as a `sql:` step today. ## The DuckDB step parse, truncate and convert zone ```sql CREATE TEMP TABLE result AS SELECT strptime('03/02/2026 14:30', '%d/%m/%Y %H:%M') AS parsed, date_trunc('month', DATE '2026-02-10') AS month, dayname(DATE '2026-02-10') AS weekday, strftime(timezone('Australia/Sydney', TIMESTAMPTZ '2026-02-10 00:00:00+00'), '%Y-%m-%d %H:%M') AS sydney; SELECT * FROM result; SELECT CASE WHEN ((SELECT parsed = TIMESTAMP '2026-02-03 14:30:00' AND month = DATE '2026-02-01' AND weekday = 'Tuesday' AND sydney = '2026-02-10 11:00' FROM result)) THEN 'as expected' ELSE error('a date did not parse, truncate or convert to Sydney time as expected') END AS verdict; ``` The statement builds its own data. It needs nothing installed beyond DuckDB itself. ## Variants - Test a time of day: Test whether the time of day of a value lies between two bounds. - Build a date from its parts: Make a date, time or timestamp from numbers such as year, month and day, or replace one part of it. - Convert between date and time types: Move date and time values between a tool's date types, such as legacy and current types. - [Find the time between two dates](https://meridian.online/operations/parse-a-date-or-time/find-the-time-between-two-dates): Compute the interval or the count of units between two dates or times. - Set a display format: Change how date and time values are shown without changing the stored values. - [Work with durations](https://meridian.online/operations/parse-a-date-or-time/work-with-durations): Parse, format, decompose and compute on durations and intervals as values of their own. - [Convert to and from epoch numbers](https://meridian.online/operations/parse-a-date-or-time/convert-to-and-from-epoch-numbers): Turn a Unix epoch number into a timestamp, or a timestamp into one. - [Extract a part of a date](https://meridian.online/operations/parse-a-date-or-time/extract-a-part-of-a-date): Take a component such as the year, month, weekday or hour out of a date or time as its own value. - [Format a date as text](https://meridian.online/operations/parse-a-date-or-time/format-a-date-as-text): Write a date, time or timestamp out as text by a format pattern. - Date and time function libraries: A tool's whole set of date and time functions, covering parsing, formatting, parts and arithmetic together. - Get the current date and time: Return the date or timestamp at which the run happens. - Parse text into a date or time: Turn text into a date, time or timestamp, by a format pattern or by inference. - [Shift a date by an interval](https://meridian.online/operations/parse-a-date-or-time/shift-a-date-by-an-interval): Add or subtract an amount of time to a date, time or timestamp. - [Convert between time zones](https://meridian.online/operations/parse-a-date-or-time/convert-between-time-zones): Attach, change or convert the time zone of a timestamp. - [Round a date down to a unit](https://meridian.online/operations/parse-a-date-or-time/round-a-date-down-to-a-unit): Truncate or bucket a date or time to the start of a unit or a fixed interval. ## What other tools call it Meridian's classification; an independent blind rating agreed on 86.2% of 312 rows (exact class, version 2). -
