Frequently Asked Questions

What are the traditional Western wedding anniversary names?

Western tradition assigns a material or theme to each anniversary year. Key milestones: 1st=Paper, 5th=Wood, 10th=Tin/Aluminum, 15th=Crystal, 20th=China, 25th=Silver, 30th=Pearl, 40th=Ruby, 50th=Gold, 60th=Diamond. These are cultural conventions, not obligations.

Are there Vietnamese wedding anniversary traditions?

Vietnamese couples often celebrate key anniversaries with family gatherings and offerings at the ancestral altar. The 25th (silver) and 50th (gold) anniversaries are particularly significant. Specific customs vary by region and family tradition.

Why might the months_married output be approximate?

The months calculation uses a simple formula based on the difference in month numbers. It does not account for the exact day within each month, so it may be off by one month near the anniversary date. The years_married output is the precise figure.

Vietnamese Lunar Age Calculator (Tuổi Mụ & Tuổi Ta)

Calculate both Vietnamese age systems from your birth year. Tuổi ta (tuổi đời) is the standard calendar age: current year minus birth year. Tuổi mụ is the traditional Vietnamese lunar age, which counts the birth year itself as year 1 — so a person born in 1990 is already 1 year old at birth and turns 2 on the next Lunar New Year. Tuổi mụ is commonly used in traditional ceremonies, paperwork, and cultural contexts in Vietnam.

Lunar Calendar Converter (Solar ↔ Lunar)

Estimate the approximate Vietnamese lunar calendar date from a solar (Gregorian) date. Enter a year (2020–2027), month, and day to get the estimated lunar month and day. Note: this uses a simplified approximation based on the Lunar New Year offset — for exact dates, use a dedicated lunar calendar application.
