Finding Government Bond Maturities

Hello ,
I have an issue, i am unable to find the maturity of Government bond.
I thought to look at euronext but most country doesn't use euronext,do you know where i should look ?

Which country is it that issues the government bonds you are investigating?

Be careful with bonds. At this point of time the interest you get might not be worth the risk.
Of course, if you choose a country that is solid, the risk of default might be low, but there you will also be getting low interest.
If the interest is lower than inflation, you`ll lose.
