Vietnamese Calendar

com.am-lich/vietnamese-calendar

This server handles conversions between Gregorian and Vietnamese lunar calendar dates, which is essential if you're building apps for Vietnamese users or dealing with traditional festivals and holidays. You can query lunar dates, get cultural context about specific days, and understand the significance of dates in Vietnamese tradition. Reach for this when you need to display lunar calendar information, calculate festival dates like Tết, or provide culturally relevant scheduling features. It saves you from implementing complex lunar calendar calculations yourself or maintaining lookup tables for Vietnamese cultural events.
