Welcome to our Summer Calendar, a wide selection of events around the country in the next seven weeks that are suitable for families. The listings have been drawn up using information supplied by VisitBritain. You can find many more events in your area on its website (<a href="http://www.visitbritain.com" target="NEW">www.visitbritain.com</a>). Dates can change, so before making elaborate plans you should check the VisitBritain website or those of the individual events, or call the phone numbers provided.

There are many other events of a smaller, more local character listed on the websites of your local council, and organisations such as the National Trust, RSPB, Wildfowl and Wetlands Trust, Forestry Commission, Woodland Trust, and English Heritage. Virtually all of their major venues and reserves have events such as guided walks, mini-beast safaris, junior archaeology days, circus skills workshops, living history days, sandcastle contests, pirate days, and other family activities throughout the summer.

We have put a sprinkling of these events throughout our listings and cheated a little with Week Five to include August Bank Holiday events. Events lasting longer than a week are listed in the week they begin, so if you are interested in a particular week, check the weeks preceding it as well. We begin with those events that last all summer long.

Happy Families: An Online Guide

Every summer holiday needs a couple of big days out: where you set off early, take a picnic, attend an event and get home late and tired, but satisfied.

Look on the internet and there's something to suit every family. What's on When ( www.whatsonwhen.co.uk) is a gargantuan site that covers Britain and abroad: internet festival in Burkina Faso, anyone? Closer to home, there is a kids and family option which offers a vast range. For example, the Bristol Children's Festival, with theatre, puppeteers, clowns and storytellers, takes place this Friday to Sunday, while the Coventry Kite Festival runs across the weekend of 13-14 August. For its size, this site is surprisingly user-friendly and searches can be refined for any region of the UK.

A proper country fair has universal appeal for adults, animal-crazed tots and horse-mad teens alike and Country Life's website ( www.countrylife.co.uk) has a comprehensive listing with phone contacts for shows up and down the country from the Anglesey County Show (9-10 August) to the Bowmore Blair Castle International Three-Day Event and Country Fair in Perthshire (25-28).

If you're looking for a festival, www.efestivals.co.uk is the site to check. It has details of everything from the newly extended Waveney Valley Festival in Norfolk, which this year runs from 5 to 8 August, to the truly fabulous Big Green Gathering, which runs from 3-7 August in the Mendip Hills near Cheddar, Somerset.

Green issues are on everyone's mind at the moment and what better way to introduce children to them than at Britain's largest and liveliest green event? "This festival offers many of the greener highlights that you might find at Glastonbury or Womad, with the emphasis on a healthy, family friendly atmosphere," say the organisers.

London's Notting Hill Carnival ( www.mynottinghill.co.uk, 28-29 August) is the largest but not the only one of its kind. See www.lccarnival.org.uk for details of the Leicester Caribbean Carnival, the largest multicultural event in the Midlands. The celebrations culminate each year on the first Saturday in August. The Nottingham Caribbean Carnival, one of the most colourful and energetic events in Nottingham's summer calendar, will take place over the weekend of 13-14 August. See www.nottinghamevents.org/carnival. More than 80,000 people are expected over the two days, which includes a parade on Sunday afternoon.

If you thrill to historical re-enactments, check the English Heritage website, www.english-heritage.org.uk or the events diary at www.livinghistory.co.uk. On the first weekend in August, for example, you can see feudal archers at Battle Abbey, Sussex, and on 20-21 August there is the William Wallace medieval fair in Lanark, complete with battles, falconry and archery and a medieval street market.

As well as its regular summer holiday activities, the National Trust has big events at some properties, such as the Music and Firework Weekend at Shugborough in Staffordshire (5-7 August) or the Fun Dog Show at Tatton Park in Cheshire on 7 August (classes include scruffiest dog and waggiest tail). For more information see www.nationaltrust.org.uk.

If you have a canine companion, don't let them miss out on the fun elsewhere. The Wag and Bone Show, the UK's greatest dog-related extravaganza, takes place in Windsor Great Park in Berkshire on 6 August. See www.thewagand boneshow.co.uk. Show categories include loveable rogues and most melting expression. Free canine dance classes for dog and owners together are on offer. All profits go to animal charities.

And finally, whether your special day is more likely to involve traction engines or a teddy-bears' picnic, your local Tourist Information Centre will know of it. Find these listed under the "practical information" button at the official website of the British Tourist Authority, www.visitbritain.com.
