Good to know
- Responsive width. The widget renders at
width="100%"up to a 440px maximum, so it fits sidebars and full-width sections alike. Adjust theheightattribute if your layout needs it. - Transparent background. The embed page ships no background of its own, so it blends into your site's design.
- No tracking scripts. The embed loads no analytics, cookies, or third-party trackers — just the countdown.
- Not indexed by design. Embed pages are marked
noindexand excluded from our sitemap, so they never compete with your content in search results. - Attribution included. Each widget carries a small "Powered by DaysCalculator.io" link — please keep it intact. Embeds are free.
- Always current. The countdown recomputes against the visitor's local day, so it stays correct even between our daily rebuilds.
Snippets for every holiday
