How to link to us

You are welcome to put links to Universalis in your web site. If you let us know then we will link back to you through our Links page.

You may also want to create links for use with banners, or links for RSS feeds.

And of course you may want to bookmark Universalis for yourself.

Usually you will want a link that takes people to today's Universalis content, whenever "today" happens to be. Thus if you create the link at Christmas, someone using it at Easter will see the Universalis content for Easter. You can also make links to specific dates in Universalis: there are separate instructions for this here.

1. Check that the link doesn't identify a specific date

If your link looks like this:


then remove the 8-digit number, so that it looks like this:


The first kind of link refers to a specific date - in this case, 14 May 2009 - and that is the only date it will ever display. On the other hand, the second kind, with no 8-digit number in the middle of it, will always show you the correct date when you click on it.

If you're making a bookmark for yourself, that's all you really need to remember.

2. Check that the link is for the right local calendar

The calendar you are currently using is Europe. If you want to change this, click here.

Different parts of the world have different local calendars, and you need to choose what calendar your link should point to. If your site has a strong local character (such as a parish site), make the link use that calendar. If your site has worldwide interest, you may prefer to omit the calendar name and stick to the General Calendar.

You can easily recognise whether a link has a calendar name in it. Here is a link without a calendar name:


and here is the same address set to use a local calendar:


3. Time zones

Time zones are important because it isn't the same date all over the world. When it's Thursday evening in the USA it's Friday in India.

The Universalis web pages use some JavaScript programming to work out the date.

If you are creating a link to a Universalis page, your visitors' browsers will almost certainly be using JavaScript. So all you need to do is to make sure that your Universalis link doesn't contain a time zone reference. The Universalis page will sort things out for itself when a visitor opens it.

You can easily recognise whether a link has a time zone. Here is a link without a time zone:


and here is the same address set to use a time zone 10 hours ahead of GMT:


or 4 hours behind GMT:


Links for banners

Universalis banners involve two links. There is the link to the banner – this is the link that a browser uses to retrieve an image from the Universalis server so that it can display it to the user. Because banners are images, not web pages, they don't contain JavaScript. So if you incorporate a Universalis banner into your web page, you need to think about the time zone. If you have a target audience (for instance, if this is a web site for a particular parish), use their time zone.

The other link involved with banners – the page to which the user is sent when he clicks on the banner – is an ordinary link to Universalis, so you shouldn't include a time zone reference in it.

Of course both the links – the link to the banner image and the link to the Universalis page – ought to have the right local calendar attached, as described earlier on on this page.
