Client SideThe grid at the top of this page renders today's date in every common format simultaneously — updated live each time you load the page. The most-asked formats:
MM/DD/YYYY — United States format. Used on US visa applications, tax forms, and credit-card expiry dates.
DD/MM/YYYY — UK, India, Australia, and most of Europe. The most widely used date format in the world.
YYYY-MM-DD — ISO 8601, the international standard for APIs, databases, JSON payloads, and sortable file names.
DD.MM.YYYY — Germany, Russia, and much of Eastern Europe.
YYYY/MM/DD — Japan, Korea, and China.
DDMMYYYY — compact form common on Indian government forms.
Each format row has a one-click copy button. Want a date other than today? Pick it with the calendar control at the top and every preset format updates live. Need a format we don't list (YYYY-Www-D, ddd, MMM Do YYYY, DDMMMYY, anything dayjs supports)? Type your own pattern into the custom-format field and the live preview appears beneath it.
The Tooloogle Date Format Converter takes any date you pick — today by default — and instantly shows it in DD/MM/YYYY, MM/DD/YYYY, YYYY-MM-DD, DD.MM.YYYY, ISO 8601, and 20+ other formats side by side, with a one-click copy button on each. Useful when filling out forms that demand a specific format (DD-MM-YYYY, MM/DD/YY, DDMMYY), when porting data between systems with different conventions (US vs. Europe vs. ISO), when normalizing date columns in a CSV, or simply when you can never remember whether your boss wants a slash or a dash this week.
Pick a date with the calendar control at the top — or type one in directly. The converter feeds the date through dayjs, a tiny battle-tested date library, and renders it in every preset format on the page. Each result row has a copy button so you can grab the format you need without re-typing. The custom-format box at the top of the grid lets you build any format string from dayjs tokens; the live preview next to it updates as you type, and a copy button is provided there too. Your custom format is remembered in localStorage, so the next time you open the page your preferred format is already filled in.
Today's date pre-filled — the page loads with today's date already shown in all 21 formats. No clicks required.
21 preset formats — covers DD/MM/YYYY, MM/DD/YYYY, YYYY-MM-DD, DD.MM.YYYY, ISO formats, plus YY/MM/DD, DDMMYY, MMMDDYY, MMM D YYYY, and many more.
Custom format builder — type any dayjs format string for instant output (YYYY-MM-DDTHH:mm:ss, ddd, MMM Do YYYY, [Quarter] Q [of] YYYY, etc.).
Custom format remembered — your last-used custom format is saved in localStorage and pre-filled on next visit.
One-click copy — every formatted result has a copy button.
Live updates — change the date and every format updates simultaneously; type in the custom format and its preview updates as you go.
Browser-only — runs locally; no upload, no analytics on your dates.
SSR-friendly — the page renders today's date in every format on the server, so search-engine crawlers and slow connections see the answer instantly.
Today's date is shown by default — in every preset format, with a one-click copy button on each.
Pick a different date with the calendar input at the top if you need one other than today.
Read the formatted versions — every preset format appears below in a two-column grid: format on the left, formatted value on the right.
Copy the format you need with the copy button next to the value.
(Optional) Type a custom format in the box at the top of the grid. The live preview appears next to the input. The format string follows dayjs tokens (YYYY, MM, DD, HH, mm, ss, ddd, MMM, Do, etc.).
Your custom format is saved for next time — refresh and it's still there.
Finding out today's date in a format your form demands — MM/DD/YYYY for a US application, DD/MM/YYYY for an Indian or European one, YYYY-MM-DD for an API request. Filling out government, banking, or medical forms that demand a specific date format (date of birth in DD-MM-YYYY, expiration in MM/YY, ISO YYYY-MM-DD for an API request body). Filling out US visa applications and tax forms that want MM/DD/YYYY when your local convention is DD/MM/YYYY. Filling out European forms that want DD/MM/YYYY or DD.MM.YYYY when your default is MM/DD/YYYY. Renaming files and folders with a leading sortable date (YYYY-MM-DD-report.pdf). Generating database query parameters that demand ISO format. Preparing import-ready CSV columns where the spreadsheet must be in YYYY-MM-DD for a database load to interpret the column as a date. Resolving the ambiguity in a date like 05/06/2026 — is that May 6th (US) or June 5th (Europe)? — by pasting it into both MM/DD/YYYY and DD/MM/YYYY slots and seeing which one matches your intent. Generating filename-friendly dates without slashes. Producing log-line-friendly dates (2026-05-06T14:30:00). Generating headline dates for blog posts (May 6th, 2026). Cross-checking a date written in DDMMMYY format on an old document.
There is no single global standard, only regional conventions:
DD/MM/YYYY (day first) is dominant in the UK, India, Australia, most of Europe, most of Africa, most of South America, and the rest of the Commonwealth. Example: 6th May 2026 written as 06/05/2026.
MM/DD/YYYY (month first) is dominant in the United States and a handful of other countries. Example: same date written as 05/06/2026.
YYYY-MM-DD (year first, ISO 8601) is the international standard for unambiguous machine-readable dates — recommended for filenames, log files, JSON payloads, database queries, and any context where two humans from different regions might disagree on a numeric-only date. Example: same date as 2026-05-06.
DD.MM.YYYY (dots) is the dominant European calendar style in Germany, Russia, and several Eastern-European countries.
If you're writing a date for an international audience and the format isn't fixed by the form/system, prefer YYYY-MM-DD or write the month name in full (6 May 2026) to remove ambiguity entirely.
The custom format box accepts any dayjs format token. The most useful tokens:
YYYY — 4-digit year (2026); YY — 2-digit year (26).
MM — 2-digit month (05); M — 1- or 2-digit month (5); MMM — short month name (May); MMMM — full month name (May).
DD — 2-digit day (06); D — 1- or 2-digit day (6); Do — ordinal day (6th).
HH — 24-hour hour (14); hh — 12-hour hour (02); mm — minutes; ss — seconds; A — AM/PM; a — am/pm.
ddd — short weekday (Wed); dddd — full weekday (Wednesday).
Square brackets escape literal text: [Year] YYYY → Year 2026.
Use ISO 8601 (YYYY-MM-DD) for any date you store, sort, or transmit programmatically — it's the only format that sorts correctly as a string. Use MMM (short month name) instead of MM whenever a date is meant for human eyes — 6 May 2026 is unambiguous; 06/05/2026 is not. When filling a form, always read the example placeholder text rather than guessing the expected format. When designing your own forms, label fields explicitly (DD/MM/YYYY) instead of relying on the user's locale. For filenames, the order YYYY-MM-DD puts the year first so files sort chronologically when listed alphabetically. For database columns, store as a proper DATE or DATETIME column type, not a string — format only at display time. Watch out for two-digit-year ambiguity (YY) — 26 could be 1926, 2026, or 2126; always store and transmit four-digit years.
The Tooloogle Date Format Converter runs entirely in your browser using dayjs, a 7KB JavaScript library. The dates you enter are not uploaded; only your last-used custom format string is stored locally in localStorage. Verify with DevTools that no requests fire as you change the date. The page also renders a meaningful default (today's date in every format) on the server so the formatted dates are visible to search-engine crawlers and to users on slow connections before JavaScript loads.
Today's date in MM/DD/YYYY (US format) is shown at the top of this page — rendered live and refreshed each time you load. Use the copy button next to the MM/DD/YYYY row to grab it instantly.
Today's date in DD/MM/YYYY (UK, India, Australia, and most-of-Europe format) appears live at the top of this page alongside MM/DD/YYYY and 19 other formats.
Today's date in YYYY-MM-DD (ISO 8601, the standard for APIs, databases, and sortable file names) appears live at the top of this page. Use this format inside code, JSON, and database queries.
US official forms use MM/DD/YYYY. The format is shown in the top row of the grid above — copy it directly to avoid typos. Double-check that the year is four digits, not two.
The order of day and month differs by region — the US writes month first, most of the rest of the world writes day first. ISO 8601 (YYYY-MM-DD) avoids the ambiguity by putting year first and is the format you should use whenever a machine, not a human, will read the date.
Excel displays today's date in the locale of the operating system — MM/DD/YYYY on US installs, DD/MM/YYYY on UK installs. Inside the underlying spreadsheet the date is stored as a serial number; the display format is configurable per cell. If you're exporting to CSV for another system, force YYYY-MM-DD to avoid locale-dependent corruption.
Tooloogle's converter shows you today's date in every common format at once — instead of switching between "DD/MM/YYYY" and "MM/DD/YYYY" and "YYYY-MM-DD" pages, you get all 21 in one view, each with a one-click copy button. The custom-format builder covers any dayjs token combination for the rare formats not in the preset list, and your last-used custom format is remembered. Browser-only processing keeps your dates private and the tool fast. SSR rendering means today's date shows up immediately on page load — no "Loading..." placeholder. Bookmark the page next to your form-filling browser, your spreadsheet, or your database client. Pair the converter with the Tooloogle Days Between Dates calculator when you need date arithmetic, the Date Calculator when you're adding/subtracting days, and the Age Calculator for date-of-birth math.
