No. These tools finish in the browser.

Is my text or audio uploaded?

No. The file and the words stay on this device.

Yes. Momentmark does not add a watermark.

It is the mean phase for that date, good enough for a gift. Rise, set, and the exact terminator need a location and an astronomy library — later.

Not on this page. A star map needs a sky catalog. Moon first; sky later.

You remember the night. This is the moon that was up, as a print.

Pick a date. The disc is the moon that night — birth, a proposal, a last evening. Lighter than a star map.

This tool runs in your browser. The words, audio, and photos are not uploaded. You do not need an account.

1
Choose the date. Time is optional; the phase changes slowly.
2
Pick dusk or paper. Add a caption if you want the date on the print.
3
Download PNG or SVG. This is a mean lunar phase, not a photograph of that sky.

The moon on the day someone arrived. Pair with the birthday clock for the hour.

The night you asked. Full or a sliver — both read as a disc.

Same date, every year the moon is different. Print the original night.

Work stays in this browser. Nothing is uploaded.
Exports are PNG and SVG. They are not a certificate, a medical record, or a legal document.
Very long text can crowd a square print. Short phrases read as jewelry; paragraphs read as a poster.
Phase is an approximation from a mean synodic month. Not a planetarium. Star maps are a later tool.
