About this tool
Generate Nepali birthday messages with formal tapai and casual timi tone, in Devanagari or Roman.
The Nepali Birthday Wishes Generator writes complete birthday messages in Nepali, in Devanagari or Roman letters, and switches the whole sentence between the polite तपाईं (tapai) register and the casual तिमी (timi) register rather than just swapping a pronoun. That distinction matters because Nepali verb endings change with it — rahanuhos is polite, rahanu is casual — and getting it wrong is the most common mistake non-native writers make. Relationship terms follow Nepali usage, including the separate words for elder and younger siblings: dai, bhai, didi and bahini.

Casual and formal versions are written separately, with matching verb endings, not machine-swapped.
Offers dai, bhai, didi and bahini instead of one generic word for brother or sister.
Every message exists in both, so you can match whichever script the recipient actually reads.
The standard phrase is 'जन्मदिनको हार्दिक शुभकामना' (janmadinko hardik shubhakamana), meaning heartfelt birthday wishes. 'शुभ जन्मदिन' (subha janmadin) is the shorter, more literal 'happy birthday'.
तपाईं (tapai) is the polite second person, used for elders, teachers, colleagues and strangers, and it takes verb endings such as -nuhos. तिमी (timi) is casual, used for friends, younger siblings and children, and takes endings such as -nu. There is also तँ (ta), which is intimate or rude depending on context and is best avoided in a written greeting.
Both use Devanagari, Unicode block U+0900 to U+097F, so the letters look the same, but the vocabulary and grammar differ. A Hindi birthday message will be broadly understood in Nepal yet will read as foreign; the wording here is Nepali, not transliterated Hindi.
Dai (दाइ) means elder brother and bhai (भाइ) means younger brother; didi and bahini are the equivalent pair for sisters. Nepali speakers use these terms for cousins and even close family friends, so pick the one that matches relative age rather than blood relation.
