Test Date Generator — Dummy Dates for Fixtures

Generate synthetic dates, datetimes, and times for databases, fixtures, and form tests. Not a calendar, countdown, or timestamp converter.

Test dates — developer notes
Synthetic date, datetime, and time strings for fixtures and DB seed. UTC only. Not a calendar, countdown, or timestamp converter.

How generation works

Pick a quantity (1–100), kind, range, format, and order. Changing an option refreshes the list immediately. Copy all or download JSON, CSV, SQL, or TXT. All instants are UTC; datetime ISO strings end with Z.

Options

Quantity (1–100)
How many rows to emit for seed jobs. Capped at 100.
Kind
date emits YYYY-MM-DD for DATE columns and HTML date inputs. datetime (default) emits timestamptz-shaped instants ending with Z. time emits HH:mm:ss and ignores the calendar range.
Range
Inclusive UTC window from today: last 30/365 days, next 365 days, around now (±30 days), adult DOB (ages 18–80), or a custom from/to. Custom from > to yields no rows. adultDob does not switch kind.
Format
Visible encodings depend on kind. ISO datetime is the datetime default (RFC 3339 Z profile). Date-kind also offers named DMY presets (17.03.2026 / 17/03/2026) — not a custom token field. SQL DATETIME has no timezone suffix. Unix for date-kind is UTC midnight of that day. Locale uses the page language via Intl.
Order
random (default) scatters values. ascending sorts oldest first so created_at seed looks true under ORDER BY. descending sorts newest first (ORDER BY DESC).

Examples

Test date FAQ

Fixtures, UTC, and what this tool is not

I searched for a random date generator. Is this it?

If you need dummy dates for fixtures, DB seed, and form QA, yes. If you need a party picker or a single lucky day, this page will not do that — it generates a pasteable list for developers.

Is this a fake date generator or birthday generator?

It emits synthetic dates, including an adult-DOB range (ages 18–80). It does not look up famous birthdays, zodiac, or holiday names. Generated dates can coincidentally match a real birth date.

Is this a unix timestamp converter?

No. You can format output as Unix seconds or milliseconds for fixtures, but this is not a live clock or epoch converter. For converting a real timestamp, use a dedicated converter.

Why is kind=date Unix midnight UTC?

A DATE has no time-of-day. Unix for date-kind is Date.UTC(y, m-1, d, 0, 0, 0) so seed jobs get a stable midnight instant. Datetime Unix is the instant itself. Time-kind Unix is seconds from midnight (0–86399), not an epoch.
