There are whispers this could be week the Greece finally manages to agree a deal with its creditors, unlocking billions of euros and staving off bankruptcy.
Greece must pay €1.6bn (£1.2bn) to the International Monetary Fund (IMF) between now and 19 June - starting with €300m (£218m) due on Friday. If it misses this deadline it'll get a 30-day grace period.
The cash-strapped country desperately needs to agree a deal with its lenders to unlock a €7.2bn tranche of bailout money before this.
The below chart by non-partisan policy think tank Open Europe shows the huge task Greece's government will have in order to meet all of the key payment deadlines which fall over the next four months.
