# Problem A

Astro

Ivica and Marica are attending astronomy classes and are
observing two unusual stars. They noted the time when each of
them flashed. They further noticed that each of the stars
flashes periodically, at regular intervals, and now they are
wondering: on what day, at what hour will the stars flash at
the *same* minute for the *first time*?

For example, if the first star flashed today (Saturday) at $02$:$20$ and the second one at $13$:$00$, with the first star flashing every $05$:$50$ (every $5$ hours and $50$ minutes) and the second every $01$:$00$ (each hour), then the first one will flash again at $08$:$10$ and $14$:$00$, and the second one at $14$:$00$. Therefore, both stars will have flashed at the same minute today at $14$:$00$.

Note that the time $00$:$00$ (midnight) is the first minute of a day.

## Input

Four lines containing four timestamps in $HH$:$MM$ format (hours:minutes), with $00 \le HH \le 23$, $00 \le MM \le 59$.

The timestamps are, in order: the time of the first star’s flash, the time of the second star’s flash, the time between consecutive flashes of the first star, the time between consecutive flashes of the second star.

The first two timestamps will differ, and both fall on the
same day – *Saturday*. Flash intervals will not be
00:00.

## Output

If the stars will never flash at the same minute, output
“`Never`” in a single line.

Otherwise, output in the first line the name of the weekday of the first same-minute flash. A reminder on the correct spelling of weekdays: “Sunday”, “Monday”, “Tuesday”, “Wednesday”, “Thursday”, “Friday” and “Saturday”.

In the second line, output the timestamp of the first same-minute flash, in $HH$:$MM$ format (with a leading zero for $HH$ and $MM$ if they are less than $10$).
