Dear Pritee, Your idea is praiseworthy but needs little bit change. Do you find it proper a couple decides a Honeymoon on 1st anniversary of wedding. Same like celebration of Birthday at the end of the month. Do one thing - Celebrate it either on the previous day after the Office hours or on the birthday at Lunch hour and in that case inform in advance to the colleague about the celebration. That will be a real feeling of satisfaction. Thanks.
