Celebrate a birthday by donating

Pinkishe Foundation

8/11/2026

A birthday is a day to count our blessings. More and more people mark it by giving. Some donate on their own birthday. Some ask friends to donate instead of buying presents. Some parents donate on a child's birthday, so the day means a little more.

One birthday, one year for a girl

A birthday begins a new year of your life.

₹1,100 covers one girl's menstrual protection, education and support for a year. The support is our menstrual helpline, free and confidential, which answers at any hour on 85888 70999.

Since 2017, we have given over 77 lakh free sanitary pads to girls and women across India (as of 30 September 2026).

Ideas for a birthday

Donate on your birthday. ₹1,100 for one girl's year, ₹2,200 for two girls, or any amount you choose.
Ask for donations instead of presents. Share our donation page with friends and family, with a line from you.
Start a monthly donation from your birthday. Choose "monthly" on the donation page.
Pool it at work. Colleagues often collect for a birthday. Donate the collection in the birthday person's name.
For your daughter's birthday. If she is growing up, read The Period Fairy with her, our free comic about the first period, in 29 languages.

A birthday fundraiser, the simple way

We do not offer personal fundraising pages. You can still collect for a birthday in four steps:

Give it a name, for example "Meera's 40th".
Share our donation page link with friends and family.
Ask each of them to forward their donation receipt to info@pinkishe.org, with the birthday name.
We add up the donations people tell us about and send you the total.

We keep these names only for this, and we never publish them.

Common questions about tracking your cycle

A few things people often ask us about cycles and about this calculator.

How accurate is this ovulation calculator?

It uses the standard calendar method. Ovulation is estimated at about 14 days before your next period, and the fertile window as the five days before ovulation plus ovulation day itself. For a fairly regular cycle it is a good guide. It cannot sense what your body is doing on a given day, so please treat it as an estimate rather than a test.

What exactly are my fertile days?

They are the days when pregnancy is possible. Sperm can survive up to about five days, and the egg lives for roughly a day after ovulation. That is why the calculator marks a window of about six days rather than a single day.

What if my cycle is irregular?

The calculator assumes your cycle stays close to the length you entered. If it varies by more than a few days from month to month, the predicted dates will move as well. Noting your actual start dates for two or three months, which is what our printable tracker is for, gives you a far better picture than any single calculation.

Can I use safe days to avoid pregnancy?

Please do not rely on it. This calculator is not a method of contraception. Calendar based methods have a high failure rate in ordinary use, and they are least reliable for irregular cycles, for teenagers and around menopause. For contraception, please speak to a doctor about a method that suits you.

What does the three-month calendar show?

Your expected period days, your ovulation day, your fertile window and the remaining days, for this month and the two that follow. It is a planning aid, for travel, exams, or simply knowing when to keep supplies handy.

What the calculator cannot do

It is not a pregnancy test and cannot confirm or rule out pregnancy.
It is not a method of contraception, and should not be used as one.
It cannot diagnose PCOS, thyroid problems or any other condition.
It cannot account for hormonal contraception, which changes your cycle.

Worth speaking to a doctor about: periods that stop for three months or more without pregnancy, bleeding that soaks through protection every hour for several hours, periods lasting longer than seven days, severe pain that stops you going about your day, or bleeding between periods. None of these mean something is certainly wrong, but all of them are worth a professional opinion rather than a calculator.

Questions people ask

Can I ask friends to donate to Pinkishe for my birthday?

Yes. Share our donation page, and ask each friend to forward their receipt to info@pinkishe.org with your birthday name. We add up the donations people tell us about and send you the total.

Is a birthday donation eligible for 80G?

Yes, for donors in India. It is eligible for tax deduction under Section 133 of the Income-tax Act, 2025 (earlier Section 80G). The deduction helps only those who pay tax in India. A donation from abroad carries no Indian tax benefit.

How much should I donate on my birthday?

Every amount is welcome. ₹1,100 covers one girl's menstrual protection, education and support for a year, and ₹2,200 covers two girls. From abroad, $25 covers two girls for a year.

Before you go

Right now, a girl in India is missing school because of her period.

Not because she wants to. Because she has a torn piece of an old saree and nobody has ever explained her own body to her. You just read an article about yours. ₹1,100 covers one girl's menstrual protection, education and support for a year.
