First day of spring 2013: Vernal equinox and Proposal Day fall on March 20

The vernal equinox is Wednesday, March 20, according to The Weather Channel. It's commonly regarded as the first day of spring.

You can begin dreaming of pastels and beach trips at 7:02 a.m. EDT.

What does the vernal equinox mean? The Washington Post explains: "Astronomically, the spring equinox marks the moment at which Earth’s axis tilts neither away from nor toward the sun, resulting in nearly equal periods of daylight and darkness across the globe."

Use the day to accomplish some spring cleaning -- or get engaged.

That's right: March 20 is also Proposal Day, a holiday that encourages participants to "propose marriage to your true love!"

Good luck with that. I'll leave you with this video for inspiration. No pressure.
