Date and Time Stamp Creator

Builds a rectangular ring-bordered stamp with a chosen date on the main line and its time on a smaller subtext line, the classic 'date received' office-stamp layout. Everything is rendered locally in your browser using this category's shared stamp composer and downloads as a transparent PNG. A free online tool from Staaarter, right in your browser.

Overview

Introduction

This tool builds the classic 'date received' office stamp: a date on top and the time in smaller text underneath, all inside a ring border.

It's aimed at anyone who needs a quick, realistic-looking dated stamp graphic without opening an image editor.

What Is Date and Time Stamp Creator?

A date/time-specific wrapper around this category's shared stamp composer: it formats a JavaScript Date into an uppercase date line and a digit-group time line, then hands both to the same ring-and-text renderer every stamp tool here shares.

The default layout is rectangular, matching the proportions of a typical self-inking date stamp.

How Date and Time Stamp Creator Works

The date is split into a day/month/year main line (e.g. "26 JUL 2026") and an hour/minute subtext line (e.g. "14 32"), both uppercased and formatted for the shared bitmap font.

The composer then draws the double-ring border and centers both lines inside it, exactly as it does for any other two-line stamp in this category.

When To Use Date and Time Stamp Creator

Use it to mark up a document mockup with a realistic 'received on' or 'processed on' stamp.

It's also useful for prototyping timestamp-style watermarks for screenshots or presentation slides.

Features

Advantages

  • Formats a real date/time value automatically, no manual text entry needed for the date line.
  • Shares its ring/text rendering with the rest of this category's stamp tools for a consistent look.
  • Runs entirely client-side and produces a genuine transparent PNG.

Limitations

  • The shared bitmap font has no colon glyph, so times display as two digit groups rather than with a colon separator.
  • Only whole-minute precision is shown; seconds aren't rendered.

Examples

Stamp today's date and time

Input

date=2026-07-26T14:32

Output

A rectangular PNG reading "26 JUL 2026" above "14 32"

The date and time are split across the main and subtext lines automatically.

Stamp a past date

Input

date=2025-01-05T09:00

Output

A rectangular PNG reading "05 JAN 2025" above "09 00"

Any valid JavaScript Date value can be formatted, not just the current moment.

Best Practices & Notes

Best Practices

  • Use the rectangular default for the most realistic 'received' stamp look.
  • Pick a larger size if you plan to add this stamp to a high-resolution document mockup.

Developer Notes

The lib function validates the incoming Date, formats it into two bitmap-font-safe lines with a small MONTH_ABBREVIATIONS lookup table, and delegates all ring/text rendering to the shared createCustomStampDesign composer rather than reimplementing layout math.

Date and Time Stamp Creator Use Cases

  • Mocking up a 'received' or 'processed' stamp for a document template
  • Adding a timestamp-styled watermark to a screenshot
  • Prototyping a dated approval stamp before ordering a physical one

Common Mistakes

  • Expecting a colon in the time display — the bitmap font has no punctuation glyphs, so it's shown as two digit groups instead.
  • Passing an invalid or unparsed date string and expecting a fallback; an invalid date is rejected with a clear error instead.

Tips

  • Combine this with the PNG Rotator tool for a slightly tilted, more authentic hand-stamped look.
  • Use the Custom Stamp Design Creator directly if you need custom wording instead of a date/time pair.
