This	is	a	calendar	app	between	friends,	workers,	unknown	strangers,	because	we	are	
able	to	set	correct	permissions	to	events	so	that	right accounts	have	the	right	ability	to	access.
Events have	dash	board	that	allows	owners	or	everyone	to	update	on	this	event.	Other	
participants	could	get	notifications	when	someone	updates	the	event.	For	example,	I	have	an
event	set	on	the	deadline	of	our	project; I	can	invite	my	teammates	to	this	event,	then	we	
update	our	progress	on	the	dash	board.	If	the	deadline	is	changed,	someone	can	update	the	
event	and	all	of	us	get	notice; if	someone	is behind	the	schedule,	we	are	able	to	notice	and	give	
help;	if	someone	tackled with a	hard	problem,	everyone	knows.
