New Year's Day is every man's birthday.

In this quote, Charles Lamb suggests that New Year's Day is symbolic of a fresh start or a new beginning for everyone, comparing it to birthday celebrations. While a birthday marks the personal beginning of a person’s life, New Year's Day marks the start of a new year for all. Lamb’s statement reflects a broader, more universal perspective, where every individual can view the new year as an opportunity to renew themselves, set new intentions, and embrace the chance for change.

Lamb’s quote can be interpreted as a reminder that each New Year offers a chance for personal growth and transformation, much like the way a birthday signifies the passage of time and the opportunity for reflection. Just as birthdays bring feelings of anticipation and the desire to start fresh, New Year's Day serves as a collective moment for people to reassess their lives and look forward to new challenges and opportunities.

The idea that "every man's birthday" is New Year's Day also speaks to the universal nature of time and life’s cycles. Unlike personal birthdays, which are unique to each individual, New Year's Day is a shared experience for everyone, marking a moment when people around the world collectively reflect on the past year and look ahead to what the future holds.

Ultimately, Lamb’s quote encourages a mindset of renewal and hope, where each new year can be embraced as an opportunity for reinvention and growth. It suggests that, like a birthday, New Year's Day is a time to celebrate life, take stock of what has been accomplished, and prepare for the possibilities of the future.
