But with technology and some of our exciting ideas, it means you can still manage to have a birthday party of kinds with you best mates and extended family.
Here are a few ideas on how to enjoy your birthday even if you are self-isolating.
Get out the cocktail shakers, find the best party soundtrack and put on your going out gear for a fun birthday celebration. Why not follow it up by watching the Tom Cruise film Cocktail at the end of the evening?
Link up with your friends over video or messenger platforms as you each mix up the same cocktail or try out a variety at the same time.
If you need some recipes to get you going, Andrey Kornilov - head bartender of Moscow's most Instagram-able bar collection SIDR - is sharing easy-to-follow cocktail recipes and there are two listed below.

If you are creating one between friends, choose between one quizmaster or each household team doing a round in-turn on various themes - and then compile all the points.
Think up team names and make the questions as bizarre as you like. You could even base them on TV game shows and have fancy dress themes for the event.
And as well as toasting the winner, remember to say cheers to the birthday girl/boy too.
3. A night at the theatre
The National Theatre, the Bolshoi Ballet and the Royal Shakespeare Company are just some of the well-known worldwide theatres that are screening previously recorded performances to enjoy from your home.
Put a date in your diary, get dressed up, catch up over video or messages for a pre-theatre drink and show off your outfits. If you are just doing it within your household, why not add on a candle-lit dinner before the show with dessert at the interval.

Then dim down the lights and be enchanted by the magic of theatre - and maybe even an ice cream or drink during the interval.
Andrew Lloyd Webber is the latest to add his musicals to live screening events on his recently launched YouTube channel The Shows Must Go On.

4. Darts tournament
Hit the bullseye with a game of darts over video. Make sure everyone has set up a board at each household and then take turns over apps including House Party or Zoom.
If you need help counting down to zero, there's the Russ Bray darts scorer app from the "voice of darts", which takes care of the scoring for you.
Chatter over video or phone link as you relax through the day and gossip while browsing magazines.
Leave it to a vote among friends on which nail varnish colour to wear, dare to try out new styles and even join in an online meditation or yoga class or app together. There's plenty to choose from including Calm.
