Getting Just date of current Week given Day name string

Question

I need to get Date only given I have string day name, So far I have tried this

var now = DateTime.Now.Date;

var currentDay = now.DayOfWeek;
int days = (int)currentDay+1;
dt1 = now.AddDays(-days);
dt1 = dt1.AddHours(hour);

example "Tuesday". Get todays date bc today is tuesday

But no luck

Some more info would be helpfull. What is your expected result for 01.01.2019 for example. — Mighty Badaboom, Jan 15 '19 at 11:07
@Alex the hard part is *parsing* a localized day name into a `DayOfWeek`. Once you have that value you can calculate the difference in days between today and the target week day, eg `now.AddDays(thatDay - now.DayOfWeek)`. That of course assumes that weeks start on a Sunday and are calculated in a specific way — Panagiotis Kanavos, Jan 15 '19 at 11:25
How do *you* define current week? Different people disagree on which day transition marks the boundary between weeks (E.g. Saturday -> Sunday or Sunday -> Monday being two conventions I'm seen) — Damien_The_Unbeliever, Jan 15 '19 at 11:25
@Damien_The_Unbeliever our week starts at sunday and end on Saturday — user786, Jan 15 '19 at 11:27
