Well, ok it was actually Saturday. But it's the first time this year we've had frost that lasted after the sun came out. It was under 3 degrees celsius (or, um, I think that's about 37 degrees fahrenheit. Celsius sounds a lot colder than fahrenheit).
I'd also like to mention that I only get to walk in the daylight on weekends. During the week it's still dark when we get back from our morning walk, and it's dark before my human gets home in the evenings.
But on weekends we get to sleep in a bit, and we get daylight for our morning walk and then we go out again at lunchtime.
The days are slowly getting longer again, soon it will be spring!
