for colonial action it is in the toolttip how many turns will be needed if it is not interrupted by chance
diplomatic action is also announced in turns (how long they last) if necessary
one turn == 15 days
for further building the game operates in days.
15 days == one turn.
you can always click on the unit or structure icon and a tooltip and a colored scale show you how long you have to wait.
you also receive information if you shuffle the mouse over a city or structure field (the cricle with tiny farms / mines)
for research it depends whether you have additional financial support ordered. a rough value is that you can expect one percent more research in a turn.
but there are variables you cannot control, speeding it up, or slowing it down.
